b is not a function :b({code:2,message:“Incomplete response”} for grpcwebtext, but ok for grpcweb

Hello!

I am trying to create client for my python grpc server.

My server implements server-side streaming methods and unary calls. As follows from library documentation, if I need streaming, i should compile my proto files with mode=grpcwebtext option

But, I also have following unary call method with bytes field in request:

message SaveUserDocumentRequest {
    bytes content = 1;
}

message SaveUserDocumentResponse {
    string url = 1;
}

service MyService {
    rpc SaveUserDocument (SaveUserDocumentRequest) returns (SaveUserDocumentResponse);
}

Client code is:

uploadImage({ content }, callback) {
        try {
            let realRequest = new SaveUserDocumentRequest();
            realRequest.setContent(content)

            this.client.saveUserDocument(realRequest, {}, (err, response) => {
                if(err) {
                    console.log(err)
                    return;
                }
                callback(response)
            })

        } catch(e) {
            console.log(e)
        }
    }

if I compile my protofiles with option mode=grpcweb this rpc method works just fine (but other server-streaming methods don’t)

But if I compile my protofiles with option mode=grpcwebtext and trying to use this method, i got following exception:

b is not a function :b({code:2,message:“Incomplete response”}

Please, if you know, what am I doing wrong, let me know Thanks for your help!

Thanks for your help! Somehow, after some iterations of development I can’t reproduce this issue any more. The sad thing is that I haven’t notice, what have I change to fix it:( But now all works just fine! So thank you very much!

Oh ok… 😅 In any case, glad it works for you now! 😃
