How to fix an Azure Function (v2) failing with error “The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.”

"The resource you are looking for has been removed, had its name changed, or is temporarily unavailable." leads to a 404 error in jQuery.

This post describes one way to resolve a problem, where you receive an error like “The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.” when calling your Azure Functions.

Problem

Another day, another simple, yet kind of weird issue to solve! This time I was developing a simple Azure Function to access Microsoft Graph API. This particular issue was kind of bugging, since the error message actually had nothing to do with the actual issue and gave no pointers as to how to fix the issue!

I was just developing a function, and suddenly it stopped working, and the only error message I got was this:

In client-side code, if called with $.get(), it looks somewhat like this:

"The resource you are looking for has been removed, had its name changed, or is temporarily unavailable." leads to a 404 error in jQuery.

“The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.” leads to a 404 error in jQuery.

So, what did I do to cause this?

Steps to reproduce:

For me, this is the way I caused the error.

  1. Create an Azure Function that takes in GET argument(s) using the beta version of the CLI (2.1, in my case)
  2. Call the function from any other source, passing arguments of varying length
  3. Suddenly you notice, with quite a few different arguments, you only get this error from the Azure function: “The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.” It doesn’t happen with all arguments, though!
  4. When the issue is underway, even if you attach the remote debugger to your Azure Function, it won’t fire, at all – so debugging is kind of difficult!

But what on Earth causes this?

Fixing an unhandled exception about StructureMap configuration failing (messed up assembly bindings)

Obama congratulates you on your broken apps

So, you’re running a console program, but while you try running it, you get an error like this: “StructureMap.Exceptions.StructureMapConfigurationException”, with a message like this: “Unable to find the exported Type’s in assembly” (the typo done by Microsoft, not me). There’s a number of reasons for this error, but for a fair share of the time that’s just your assembly bindings being messed up. Luckily, that’s another easy fix!  Continue reading

Solving Azure Web Application’s first load perfomance issues

Microsoft Azure logo

Is your Azure Web Application suffering from absolutely horrible load times every time someone accesses it for the first time every 15 minutes or so? Mine was. It was pitiful.

I was developing a web-based service using EF6 and ASP.NET MVC 5, where all the assets were hosted in the Azure. Even though the app was reasonably lightweight and usually responded very fast, the first time someone accessed it in a while it took 20-60 seconds to load AND sometimes even timed out (especially with mobile clients). Load testing revealed only the what I already knew: initial load times were horrendous, but after that everything worked fine. I did eventually find the solution, though!

Hackathon win: Resolving Managed Metadata Madness

Won my first hackathon!

I won a hackathon! They had fun topics, it was a cool challenge, a well organized event, and had cool prizes. Since this is the first hackathon I ever took part in, I thought I’d post something about my experience and the solution(s) I figured out. Continue reading

Solving error “AADSTS90013: Invalid input received from the user”

AADSTS90013: Invalid input received from the user. (header thumbnail)

I stumbled upon a customer, that complained about some pages in their intranet throwing weird errors with authentication. Those pages seemed to have one thing in common – there was a Yammer embed (or a SharePoint script webpart with Yammer embed script in it, to be precise) there. The error code they got was “AADSTS90013: Invalid input received from the user”.

Below, you can see an example of the error screen.

AADSTS90013: Invalid input received from the user.

AADSTS90013: Invalid input received from the user.

Okay – this is going to be extremely specific, and probably won’t solve the issue for all of you out there! But this is what worked for this customer: Continue reading

How to Resolve Managed Metadata Madness in SharePoint?

Microsoft Flow that's used in this demo - it uses an Azure Function to extract text from a doc, which is then sent to Text Analysis, and finally written back to SharePoint. In the end, it sends notifications of the status of the run.

Using Azure Functions and Cognitive Services Text API to enrich a Flow that fills Metadata for new items in a Modern SharePoint Team Site. That’s, in a nutshell, the solution I submitted to a recent online hackathon. Quite a mouthful, isn’t it? The whole solution (and a public vote, if you’re interested!) is available here: https://devpost.com/software/resolving-managed-metadata-madness-in-sharepoint – this blog post will describe the solution and the reasoning behind it.

Preface

Some time ago my manager asked me to take a few weeks off, since I had accrued quite a lot of overtime during the hectic months working for Valo. I got bored quite quickly, so I was pretty happy to encounter an online hackathon organized by Devpost. I wasn’t aware of them beforehand, but they seemed to have hosted quite a few interesting hackathons before. Some of which quite interesting, I might add! This prompted me to also take part into a hackathon they were just hosting: “Work smarter, not harder with Office 365.”

I’m not a huge fan of hackathons, but the topic was too good to miss, so I submitted a solution I’d been thinking about implementing, but didn’t have a good enough reason to implement it for customers.

Description of the issue

So, which issue am I aiming to solve? Let’s see… 

  • The amount of data is surging (~90% of the data in the world has been created in the last 2 years)
    • To ensure that data in organizations is useful, you need to make sure, that your users find it easily!
  • A great “Enterprise-y” solution has been metadata tagging!
    • However, users generally hate doing that manually
    • Automatic solutions are either cumbersome to maintain, expensive to develop, or both
    • Many required metadata fields will cause users to migrate to shadow IT solutions (like DropBox) – or not use any collaboration solutions at all!

Call to sites Graph API requires “owner” permissions for site collection regardless of app permissions

Okay – yet another weird issue, and a hacky workaround. I was developing an app that was calling a SharePoint site through Graph API, using jQuery $.ajax call (developed in TypeScript), and ran into surprising 401 errors. I did find a workaround, but am also working on an actual fix.

Description

To get SharePoint site ID, which is needed when accessing SharePoint lists, the calls seemed to fail for my test accounts. Everything was working fine for my developer account, which was a global admin, so the first thing I was suspecting was of course permissions…

The first offending test account was a Group member, and a restricted reader in the site collection I was trying to access via Graph. The account was also a contributor on the root site of the tenant. And all of my accounts were licensed with E3/E5.

I knew that this part of the code was supposed to get a site id for a certain SharePoint site collection with a call to Graph API, similar to this one:

https://graph.microsoft.com/v1.0/sites/<tenant>.sharepoint.com:/sites/<site>/

It worked for my developer account, but just wouldn’t work for the test accounts! This is the error I got: Continue reading

4 ways to fix error AADSTS65001 (The user or administrator has not consented to use the application)

Azure AD Login error

Fixing issues with Azure AD authentication for Enterprise applications can be tricky. This article contains multiple different fixes to an issue, where granting admin consent has somehow failed. Not all of the different solutions will work for all situations, though! That’s why I included a couple of different options to try… 🙂

Why do you even get issues with Admin Consent (like AADSTS65001)?

Imagine this: You’re trying to add or use an app, but the requires such permissions from your tenant, that only an administrator can grant.

Typically to add this kind of an app, you’ll have to be a global administrator. If it’s an enterprise application, it could also be in an invalid state after someone tried adding the app without sufficient permissions.

Our investigation was focused on a mobile app, that’s deployed as an enterprise app. Most of the things should apply for web-based apps or console programs or whatever else you’re deploying, too.

The whole error might look something like this: Continue reading

Getting Connect-MsolService (and other SharePoint Online cmdlets) to work

Connect-MsolService

In this post, I’ll try to archive everything you need to download and install to get commandlets like Connect-MsolService working. I’ve had to do it a couple of times when changing laptops, so it’s good to document them somewhere! 🙂

I’ll try to even keep this updated as things change.

Required installations:

  1. Microsoft Online Services Sign-In Assistant for IT Professionals RTW
    1. https://www.microsoft.com/en-us/download/details.aspx?id=28177
  2. SharePoint Online Management Shell
    1. https://www.microsoft.com/en-us/download/details.aspx?id=35588
  3. Windows Azure Active Directory Module for Windows PowerShell (v1)
    1. http://connect.microsoft.com/site1164/Downloads/DownloadDetails.aspx?DownloadID=59185 
      1. Update 5.3.2018: Microsoft actually moved this documentation, and apparently hid it behind authentication somewhere (might require Global Admin or similar on your tenant to even READ IT… That’s smart.)
      2. If you installed it before, it’ll still work, but if you didn’t, never mind. Just see this step.

Now, to run cmdlets like “Connect-MsolService”, just start SharePoint Online Management Shell (or PowerShell).

If you also need Azure Remote Management (AzureRM) cmdlets (I always do!), run this in an elevated PowerShell:

What to do if Microsoft hid the AAD module for PowerShell?

Fear not – only the last step (step 3) changed! Instead of installing the AAD module, you run this on PowerShell: Continue reading

Applying Entity Framework’s Code-First Migrations against a Database in Azure by running Update-Database

This post describes how to run Entity Framework’s code-first migrations against a database located in the Windows Azure. This is done by running Update-Database commandlet with suitable switches, see below.

The problem and symptoms

Okay, so you’re developing your MVC+EF cool web app with a database in Azure, and you’re using code-first migrations. Cool! What’s nice with code-first-migrations is the fact they are run automatically even in the cloud the next time your app is running (as long as you publish your app with that little box ticked – something like in the screen capture below). But wait – what if there are conflicts – what kind of errors are you going to get?

 

Azure Web Publish

Azure Web Publish

Not very useful ones, I’m afraid, and it’s a pain navigating the Azure portal to fetch the log files. At some point – for me, it wasn’t the first time I ran the web app, but the phase when I was logging in – you’ll be getting the error the migrator internally throws. That might be enough to point you to the right direction, and maybe you’ll be able to figure out what’s wrong! But if that’s not the case, here’s the way to run Update-Database against your Azure Database!
