Cannot run Azure Durable Functions on Mac M2 PRO

Description

When trying to create and run a new Azure Durable Function (.NET 7 | Isolated), I am unable to run it successfully.

A host error has occurred during startup operation '8643db33-586e-4c53-92d0-476fbeb08331'.

Hi @apavate. I believe you may be experiencing the issue described here. Can you please review that guidance and let me know if that worked for you?

@davidmrdavid
I have tried it and failed miserably. I think that's mainly because there aren't any clear instructions.
Since this is a known issue, can you supply some clear step-by-step instructions so I can try it again?

For now as a workaround:

Add the package reference
<PackageReference Include="Contrib.Grpc.Core.M1" Version="2.41.0" />

And add this to your csproj.
<Target Name="CopyGrpcNativeAssetsToOutDir" AfterTargets="Build"> <ItemGroup> <NativeAssetToCopy Condition="$([MSBuild]::IsOSPlatform('OSX'))" Include="$(OutDir)runtimes/osx-arm64/native/*" /> </ItemGroup> <Copy SourceFiles="@(NativeAssetToCopy)" DestinationFolder="$(OutDir).azurefunctions/runtimes/osx-arm64/native" /> </Target>

This will copy the needed file to the folder required. Until there is a fix

I want to update the instructions to make it easy for other developers.

1. Add the Nuget package Contrib.Grpc.Core.M1 to the Azure Function Project by either using the Nuget Package Manager or by just adding the following line to the .csproj file.
   <PackageReference Include="Contrib.Grpc.Core.M1" Version="2.41.0" />

2. Add the following line to the .csproj file right before the last </Project> tag.
   <Target Name="CopyGrpcNativeAssetsToOutDir" AfterTargets="Build"> <ItemGroup> <NativeAssetToCopy Condition="$([MSBuild]::IsOSPlatform('OSX'))" Include="$(OutDir)runtimes/osx-arm64/native/*" /> </ItemGroup> <Copy SourceFiles="@(NativeAssetToCopy)" DestinationFolder="$(OutDir).azurefunctions/runtimes/osx-arm64/native" /> </Target>

3. Run the project and it should work!

Ok, the workaround looked promising, and my durable function compiled and started, but it crashes when invoking the function via http get call, sigh.

exception: System.AggregateException: One or more errors occurred. (Status(StatusCode="Unknown", Detail="Exception was thrown by handler.")) ---> Grpc.Core.RpcException: Status(StatusCode="Unknown", Detail="Exception was thrown by handler.")

Works perfectly for me on Apple Macbook Pro (M2 Pro). Tried creating both .net6 in-process function and .net7 isolated function, and it works in both cases.

Yes @apavate , did stupid mistake, it works for me as well on M1 Mac, thanks for the workaround!

This issue: Azure/azure-functions-host#9235 is aiming to holistically fix this, as durable will then switch to AspNetCore implementation of gRPC in the host.

Just as a heads up, we've surfaced the instructed provided here by @apavate and @vdboots in the DF isolated SDK repo: microsoft/durabletask-dotnet#148. Thanks for your contribution here :).

Hi @Hipster74 , would you mind sharing what your mistake was? I am facing the exact same issue.

Figured it out after hours, so for anyone else stumbling upon this issue in the future: for me the (stupid) issue was that I had excluded the durable function in my host.json.

I'm actually not on M1/M2, I'm on an Intel Mac on .NET 8 having this issue.

For me the following seems to be getting me by for now...

1. dotnet add package Grpc.Core
2. add target to project (note osx-x64 rather than osx-arm64 and slightly different paths than the other examples on here)

  <Target Name="CopyGrpcNativeAssetsToOutDir" AfterTargets="Build">
    <ItemGroup>
      <NativeAssetToCopy Condition="$([MSBuild]::IsOSPlatform('OSX'))"
        Include="$(OutDir)runtimes/osx-x64/native/*" />
    </ItemGroup>
    <Copy SourceFiles="@(NativeAssetToCopy)"
      DestinationFolder="$(OutDir)bin/runtimes/osx-x64/native" />
  </Target>

If I didn't do the above when I run my app it looks for the Grpc.Core assets in locations where they are not being output to by default.
