Crash when attempting to record gRPC interaction

Proposal

I'm attempting to record an interaction with a gRPC server, I've setup the server with the required descriptor files, but I'm seeing a crash when running in record mode:

Reproduction steps

• Follow instructions to enable the extension, compile the gRPC .dsc file then launch a docker version of the server
• Start recording and attempt to interact with a remote gRPC server

Recording isn't implemented yet, so retagging as an enhancement request.

Just want to say I'm also interested in this enhancement request. Happy to be an early tester when the time comes 😄
