How to fix “Missing value for AzureWebJobsStorage in local.settings.json”?

1. Add “AzureWebJobsStorage” value to your local.settings.json file

   Obviously, you could be missing this app setting completely – maybe by adding it somewhat like this:
   
   
   And in copy-pasteable form – this is what you should add to local.settings.json -file’s “Values”-node:
   
   "AzureWebJobsStorage": "UseDevelopmentStorage=true"
   
   Simple as that! Except if it doesn’t work, try the other options below.

2. Close and reopen your Visual Studio instance

   Just in case. It’s easy, it’s quick, and it has helped me once or twice!

3. No nested values in local.settings.json

   Valid JSON can have values nested infinitely deep. Your local.settings.json file does not support that (beyond predefined “sections”, such as “Values” (for appsettings) or “ConnectionStrings”, however!
   
   Verify you’re not trying anything too fancy there.
   
   What’s a bit confusing, however, is that appsettings.json file DOES support nested configuration values. So no consistency here. 😊

4. Make sure your local.settings.json file is getting deployed (copied) to the output folder

   Modify your .csproj file to have this:
   
   <None Update="local.settings.json">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
<CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
</None>
   
   This applies at least to .NET with Visual Studio, but YMMV. 😌
