@angelinagovada Let me give you some context regarding this specific issue.

In Ballerina gRPC, we use the protoc-tool to generate the ballerina files needed for the gRPC client and service. In the current generated files, there are 2 extra lines getting added [1]. We need only 1 newline.

This fix needs to be done in the protoc-tool.

• The tool starts execution from here
• To generate the bal files, we invoke the generateSyntaxTree method.
• You can go through these and get yourself familiarized with the code.
• Once you have added the fix, you can update the existing test cases to match the new changes.

Also, if you want learn about gRPC and the protoc-tool you can follow these.
