Review comment:
It's a bit strange to continue running here, if we know it will fail
finally (will it?)
From the jira issue, looks grpc should check and handle our return value
decently.
Maybe open an issue in grpc community? If grpc is willing to change, do we
still need to update our code?
For now, I'm not sure if it's appropriate to simply abort here in release
build, with some clear error messages and hints to fix it by chunking the data.
