Uncaught TypeError: o.toArray is not a function

Hi!

I try to work with any.proto

syntax = "proto3";
import "google/protobuf/any.proto";
...
message AddJobRequest {
	string api_key = 1;
	int32 token_id = 2;
	JobAction action = 3;
	google.protobuf.Any payload = 4;
}

I compile proto under Windows with command

protoc --plugin=protoc-gen-grpc-web=protoc-gen-grpc-web-1.0.3-windows-x86_64.exe --grpc-web_out=out=Job_grpc_web_pb.js,import_style=commonjs,mode=grpcweb:JS_Campaigns Job.proto

and pack with

npx webpack client.js

My function is:

function addNewJob(api_key, token_id, action, payload, callback) {
	
	var request = new AddJobRequest();
	request.setApiKey(api_key);
	request.setTokenId(token_id);
	request.setAction(action);
	request.setPayload({ payload: payload });
	
	job_client.addNew(request, metadata, (err, response) => {
		callback(response, err);
	});	
	
}

I receive error

Uncaught TypeError: o.toArray is not a function

The same error occurs with google/protobuf/wrappers.proto What I’m doing wrong?

It’s difficult to tell why you have “proto” as undefined without looking at all your “client.js” script. For my part, just by following the basic “helloworld” example, I got this “proto” variable in my globals.

If it could help you : I was able to get some inspiration by looking at this example. Though I didn’t follow the example step by step, it was by looking at it that I discoved that there was a “fromJavaScript” function (and also a “toJavaScript”) to convert JSON to Struct.proto (and vice-versa).

Sorry I have to declare Bug Bankruptcy on some of these older bugs. But this looks like a protobuf issue. If this is still a grpc-web issue, please open a new one.
