UnsupportedPayloadTypeException when try to profile the app

[jvitor83]

Hi, I'm having a UnsupportedPayloadTypeException when try to "Profile now" at Azure App Insights.

The Exception:

[16:02:30 ERR] Trace upload failed. Exit code: 255
[16:02:30 ERR] Unexpected error happens on stopping service profiler.

The csproj:

    <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.17.0" />
    <PackageReference Include="Microsoft.ApplicationInsights.Profiler.AspNetCore" Version="2.4.0-beta1" />
    <PackageReference Include="Microsoft.ApplicationInsights.Kubernetes" Version="2.0.3-beta2" />

It is a dockerized application running on netcoreapp3.1.

Any clues about what can be happening?

Hi @jvitor83, Thanks for the report. We have had some major refactoring for 2.4.0-beta1 that's related to serialization and might caused some issue. Give us some time to investigate it.

At the same time, would you mind try it on 2.3.1 and see if that works for you?

[jvitor83]

Hi @xiaomi7732,

The 2.3.1 worked just fine.

Thank you!

@jvitor83 I am glad to hear that. A bit progress: I reproduced the exception on my box with mcr.microsoft.com/dotnet/aspnet:3.1-alpine, we haven't reach the bottom of the investigation yet. News will be posted here.

Hey @jvitor83 just wanted to keep you updated, we worked out a fix and will be deploying 2.4.0-beta2 after a bit of testing and verification. I'll let you know when it's released, hopefully in the next few days. Thanks again for spotting this! We really appreciate it.

[JacobBovee]

Hey @jvitor83 just released a new version of profiler with this fix included: 2.4.0-beta2.

Please let me know if this works for you. Thanks again for taking the time to work with us on this.
