Failed to frame message

[ric...@deepintent.com]

Hi,

I am trying to debug a situation where I have 3 GRPC services using the GRPC java. Each of the projects is a submodule of the parent maven project and I'm using java 10. 1 of my services has stopped working and the client error is saying io.grpc.StatusRuntimeException: INTERNAL: Failed to frame message.

I can include the protobuf file if it will help, but it's not a super complex interface. If anyone has any ideas on what additional steps I could take to debug, I would appreciate it. I am super confused on why 2 of the 3 services still work, and if I implement the interface in 1 of the other projects, the interface works correctly. The pom file of the 2 submodules are identical.

Thanks in advance,

Rickey

Additionally, this happens on both grpc-java 1.12 and 1.13.2.

Can you include the full stack trace?

Sure, here it is. The request message has a single string field.

What is ErrorCallbackNotImplemented ?    There should be a cause included in our exception.

We are using salesforce's reactor-grpc and that is what the original client stack trace is from. I tested with a client using the standard blocking stub and below is the stack trace. Thanks

Additionally, if run under java 8 instead of java 10, below is the stack trace. It is even less useful than before. Is there anything I can do to get more information about this error?

These various exceptions should have another "Caused by" exception underneath. "Failed to frame message" always includes an additional cause.
