ASP.NET Core gRPC JSON transcoding throws InvalidOperationException

I have a basic application and used the gRPC JSON transcoding in ASP.NET Core article to incorporate gRPC JSON transcoding. However, when I try to run my application, it gives me an error message:

System.InvalidOperationException: Error binding gRPC service 'SomeGrpcService'.
 ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
 ---> System.InvalidOperationException: The stored extension value has a type of 'Google.Api.HttpRule, Shared, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. This a different from the requested type of 'Google.Api.HttpRule, Google.Api.CommonProtos, Version=2.5.0.0,Culture=neutral, PublicKeyToken=3ec5ea7f18953e47'.

My setup is the following:
I have the following line in the *.csproj file:

<ItemGroup>
      <Protobuf Include="Protos\**\*.proto" ProtoRoot="Protos\" GrpcServices="Both" />
</ItemGroup>

and folder structure is:

Protos
  google
    api
      annotations.proto
      http.proto
  Some.proto

I believe the main issue is:

The stored extension value has a type of 'Google.Api.HttpRule, Shared, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. 
This a different from the requested type of 'Google.Api.HttpRule, Google.Api.CommonProtos, Version=2.5.0.0,Culture=neutral, PublicKeyToken=3ec5ea7f18953e47'.

and I am using Microsoft.AspNetCore.Grpc.JsonTranscoding version 7.0.9.

Can someone offer a solution to the problem mentioned above?

You must change your directory like this:

  google
    api
      annotations.proto
      http.proto
  Protos
    Some.proto

Project Directory

The following changes are fixed the issue for me:

update *.csproj file:

<ItemGroup>
      <Protobuf Include="Protos\Some.proto" ProtoRoot="Protos\" GrpcServices="Both" />
</ItemGroup>

and added the Google.Api.CommonProtos library to the project.
