Warning that Microsoft.Azure.WebJobs.Extensions.ApplicationInsights is being used but it is not (explicitely?) used

[tymtam2]

I am chasing why a function that normally works starts reporting 404 after some period of time and I am looking through Availability and Performance at portal.azure.com and the mighty Functions that are not triggering detector.

The detector reporting an issue I cannot act upon.

It says

Exception Type	Total Occurrences	Exception Message	Latest Timestamp
The Application Insights extension is no longer supported. Packa	1	The Application Insights extension is no longer supported. Package references to Microsoft.Azure.WebJobs.Extensions.ApplicationInsights can be removed.	2/28/2022 12:53:00 AM

However I don't reference this package. Referenced packages are:

  <ItemGroup>
    <PackageReference Include="Azure.Messaging.EventHubs" Version="5.6.2" />
    <PackageReference Include="Microsoft.Azure.Functions.Extensions" Version="1.1.0" />
    <PackageReference Include="Microsoft.CodeAnalysis.NetAnalyzers" Version="6.0.0">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.0.1" />
    <PackageReference Include="StackExchange.Redis" Version="2.2.88" />
    <PackageReference Include="StyleCop.Analyzers" Version="1.2.0-beta.406">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

The project is .NET6:

<PropertyGroup>
  <TargetFramework>net6.0</TargetFramework>
  <AzureFunctionsVersion>v4</AzureFunctionsVersion>
  <Nullable>enable</Nullable>
</PropertyGroup>

The function project references one project wich in turn references the following packages:

   <ItemGroup>
   <PackageReference Include="Microsoft.CodeAnalysis.NetAnalyzers" Version="6.0.0">
     <PrivateAssets>all</PrivateAssets>
     <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
   </PackageReference>
   <PackageReference Include="Microsoft.Extensions.Logging.Abstractions" Version="6.0.0" />
   <PackageReference Include="StyleCop.Analyzers" Version="1.2.0-beta.406">
     <PrivateAssets>all</PrivateAssets>
     <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
   </PackageReference>
 </ItemGroup>

Hi @tymtam2 , Thank you for your feedback! Could you please give us the function invocation id and region to check the cause.

[tymtam2]

The region is Asutralia East, but I'm not sure I can get invocation id - I don't see this problem in App Insights and it's part of a request so I'm not sure what invocation id would be here.

The function is https://portal.azure.com/#@ouijalitetest.onmicrosoft.com/resource/subscriptions/1e9450c1-bd33-4166-b3ae-5888031de772/resourceGroups/LuceoTest/providers/Microsoft.Web/sites/luceotestingest/troubleshoot and it is reporting the issue now:

[tymtam2]

Extra info: A sibling function app (in DEV environment, not in TEST environment) does NOT report these issue at the moment. I don't know if the DEV version has ever reported this as the detector's time range can only be set to at most 24h.

Possibly relevant changes between the two function apps are:

1. DEV app (no warning) has the brand new Microsoft.NET.Sdk.Functions 4.1.0

-<PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.0.1" />
+<PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.1.0" />

2. DEV app (no warning) has WEBSITE_RUN_FROM_PACKAGE set to "1"
   TEST app (with warning) does not have WEBSITE_RUN_FROM_PACKAGE set.

I hope this helps.

Hi @pragnagopa / @balag0 , Could you please look into this issue.

@gzuber / @AnatoliB for triage

I'm getting same exception with linux/python-based function apps.

Looks like it is probably caused by the runtime or extension bundle:

config of mine.

"extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[2.*, 3.0.0)"
  }

Trying updating the extension bundle soon.

Update: extension update fixed the issue.
