Calling client.AllExtensionNumbersForType when no extensions exist returns an error about protoreflect HOT 2 CLOSED

@nihar-aalyria, I'm afraid EOF is not the issue. If that is what you are seeing, then this is an actual error. The way the server is supposed to reply is to send a response message in reply to the request for extension numbers. The reflection protocol is a bidi stream, so the client sends requests as individual messages on the stream and then, in the same order as requests were sent, the server sends response messages, in one to one correspondence to the request messages.

If you have not confirmed that the server is sending an EOF, then I suspect that the issue is that the server is actually sending back an error. In responding to an "all extension numbers" request, the server can send back either an "all extension numbers" reply or an error reply.

It would be easier to hypothesize on what is happening if you include some details on the error you are seeing -- like the actual error code and message. It might also be good to include details on the server, particularl what language is it written in and (if available) what version of the relevant gRPC runtime library it is using.

Thank you for the quick reply, and apologies for the late response! I'll look into the error code and message, and re-open this issue if I have further details. Thanks!
