There, JsonFormat default printer is used, which by default convert names to lowerCamelCase.
Describe the solution you'd like
To allow preserving proto field names
JsonFormat.preservingProtoFieldNames().printer()
should be called instead of
JsonFormat.printer()
So the solution proposed is to leave the current behavior as it is and, depending on an environment variable that could be set in the container, use the "preservingProtoFieldNames" printer. This way, both approaches could be used.
Describe alternatives you've considered
Nothing. If not done we must define requests in lowerCamlCase
Is your feature request related to a problem? Please describe.
Using grpc-wiremock we have noticed that mappings must have request in lowerCamlCase. This is due to the following code: https://github.com/Adven27/grpc-wiremock/blob/830097d13bfb9e01e5f56dfd54fcb7c0a643327e/src/main/java/io/adven/grpc/wiremock/HttpMock.java#L137-L139

Additional context
No further actions needed in the response, because no matter the mapping is lowerCamlCase or snake_case, it is converted right into snake_case for protos: https://github.com/Adven27/grpc-wiremock/blob/830097d13bfb9e01e5f56dfd54fcb7c0a643327e/src/main/java/io/adven/grpc/wiremock/HttpMock.java#L143-L152
