Following the tutorial I try to run my own service and get an error. What could I have done wrong?
{ok, Connection} = grpc_client:connect(tcp, "localhost", 10000).
{ok, Stream} = grpc_client:new_stream(Connection, 'Send', 'SendMessage', speak).
** exception error: no match of right hand side value {error,<<"failed to create stream">>}
speak.proto
