If you make any edits to service.proto, you'll need to regenerate the generated protocol buffer JS files in order to use the changed protocol. First, install protoc to your system and make sure that it is in your $PATH. Then, you should be able to run yarn protoc to generate protocol buffer files for the messages and services.
