How to debug INVALID_ARGUMENT? about protobuf-ts HOT 1 OPEN

Hey Daniel, apologies for the late response. It's hard to tell what's going on just based on the code INVALID_ARGUMENT.
Looking at grpc-web-transport.ts and grpc-web-format.ts, I don't see us raising this error code 🤔

I would add add breakpoints or log statements in @protobuf-ts/grpcweb-transport to verify that the error is indeed part of the server response.

If it is, the server is most likely raising the error because it received headers or a body that it does not accept. It is possible that our client understands a part of the gRPC-Web spec differently than tonic-web. Unfortunately, the spec is quite vague. Our client runs just fine against dotnet (there's an example in this repository), and I've also been using it against envoy without issues. But it's possible that tonic does something differently. So as a next step, I'd add breakpoints or log statements in the server.
