Hi all, getting this error while using wiremock-grpc-extension standalone jar for the response type of the google.protobuf.Any

Exception in thread "grpc-default-executor-2" wiremock.com.google.protobuf.InvalidProtocolBufferException: Missing type url when parsing: {"greeting":"Hello Duis"}

I think I’ve fixed this issue here, albeit in a slightly hacky way: https://github.com/wiremock/wiremock-grpc-extension/pull/32 Would appreciate any feedback/confirmation it works in your environment.

Hi @Tom how we can do this in stand alone server. Is there can be any way the any type Request get unpack on the bases of its descriptor file and its response get pack to any type Grpc response

If you’re configuring from JSON (rather than the Java DSL) you need to include the

@type

element e.g. in: https://github.com/wiremock/wiremock-grpc-extension/blob/any-type-issue/src/test/java/org/wiremock/grpc/GrpcAcceptanceTest.java#L313

thanks Tom
