@sampajano , @stanley-cheung After successfully resolving the build issue with the protoc-gen-grpc-web plugin, I'm now encountering a new problem related to the protoc-gen-js plugin. The issue from changes in the JavaScript code generation for Protobuf, as the older implementation has been moved and is now redirected to a new repository: https://github.com/protocolbuffers/protobuf-javascript.
