TypeError: Channel credentials must be a ChannelCredentials object when creating CloudTasksClient

[Rayco Velázquez González]

I'm encountering the same problem as detailed in this GitHub issue: #77. Despite attempting the suggested workaround of aligning the @grpc/grpc-js version, the issue persists.

The error message I'm receiving is:

TypeError: Channel credentials must be a ChannelCredentials object at new ChannelImplementation

This error arises when executing the following code:

const client = new CloudTasksClient({
  port: 8123,
  servicePath: "localhost",
  sslCreds: credentials.createInsecure(),
});

The versions I'm using are:

• Npm dependency: @google-cloud/tasks: 4.0.1
• Docker image: cloud-tasks-emulator: 1.2.0

@vrayco I came across the same error

     TypeError: Channel credentials must be a ChannelCredentials object
      at new ChannelImplementation (node_modules\google-gax\node_modules\@grpc\grpc-js\build\src\channel.js:29:19)
      at new Client (node_modules\google-gax\node_modules\@grpc\grpc-js\build\src\client.js:65:36)
      at new ServiceClientImpl (node_modules\google-gax\node_modules\@grpc\grpc-js\build\src\make-client.js:58:5)
      at GrpcClient.createStub (node_modules\google-gax\build\src\grpc.js:345:22)
      at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

The root cause is that in node_modules\google-gax\node_modules\@grpc\grpc-js\build\src\channel.js:29:19 the credentials object is checked to be an instance of google-gax/ChannelCredentials

However, in the README of this repository, the @grpc/grpc-js library is used to create the CredentialsObject.

import { credentials } from '@grpc/grpc-js';

const client = new CloudTasksClient({
  port: 8123,
  servicePath: 'localhost',
  sslCreds: credentials.createInsecure(),
});

Thus, the check in node_modules\google-gax\node_modules\@grpc\grpc-js\build\src\channel.js:29:19 fails because the given credentials object has a different prototype hierarchy.

I fixed it by using ChannelCredentials from google-gax module. No need to install or pin any dependency versions.

import { ChannelCredentials } from 'google-gax';

const client = new CloudTasksClient({
  port: 8123,
  servicePath: 'localhost',
  sslCreds: ChannelCredentials.createInsecure(),
});

I am using "@google-cloud/tasks": "^5.0.0"

Here's a PR that updates the README #96

@stfsy It compiles but i still get build error Error: Dynamic require of "@grpc/grpc-js" is not supported

UPDATE: new version of cloud tasks available "@google-cloud/tasks": "^5.1.0", works after update
