TypeError: Cannot read property 'MethodInfo' of undefined with webpack 5

Hai,

I’am using protoc to compile .proto to commonjs and works fine.

the problem happen when I’m using webpack 5 with error like this:

TypeError: Cannot read property 'MethodInfo' of undefined

the error refer to auth_grpc_web_pb.js .

How to solve this problem ? Please advice, thank you

UPDATE:

I fallback to grpc-web v1.2.1 and the error was gone.

but I still dont know why this is happen to grpc-web v1.3.0

@bram-abe Thanks for the report! 😃

I suspect the issue is likely because you’re using an old version of protoc-gen-grpc-web. Could you try installing the latest version (1.3.0) following this instruction, and see if the issue goes away?

(btw i’m curious how are you typically getting your protoc-gen-grpc-web and whether we can make it easier for you to get the latest version 😃)

aah you’re right the protoc-gen-grpc-web still an old version, now the issues are gone after reinstalling. Somehow I’am missing on the middle of update all deps. process and miss to overwrite the old version protoc-gen-grpc-web with the new one and set it on windows path.

Thank You for help
