Sorry for the delay. Looking at both logs, it seems pretty clear that
Apache is dropping some data:
Server:

On the server side, you can see the gRPC server clearly setting both headers
and trailers. But on the client side, we receive empty trailers. They should
have contained "grpc-status" and "grpc-metadata". This looks like a bug within
Apache to me. I would report it to them.
