How to use insecure connection

[ottob]

Im trying to use a local emulator for Cloud Tasks that requires an insecure connection.

Im trying to construct a client like this:
"@google-cloud/tasks" is v2.1.0
"@grpc/grpc-js" is v1.1.6

import { CloudTasksClient } from '@google-cloud/tasks'
import { credentials } from '@grpc/grpc-js'

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

But get the following error:

error TS2322: Type 'import("/Users/me/myproj/node_modules/@grpc/grpc-js/build/src/channel-credentials").ChannelCredentials' is not assignable to type 'import("/Users/me/myproj/node_modules/google-gax/node_modules/@grpc/grpc-js/build/src/channel-credentials").ChannelCredentials'.
  Property 'callCredentials' is protected but type 'ChannelCredentials' is not a class derived from 'ChannelCredentials'.

20       sslCreds: credentials.createInsecure(),
         ~~~~~~~~

Found 1 error.

How can this be done?

@ottob I wouldn't expect that you need to instantiate the grpc credentials yourself. Could you try setting the apiEndpoint value to the emulator address, including port?

[ottob]

Do you mean like this?

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

Then I get his error from the call to createTask: Error: 14 UNAVAILABLE: No connection established

Hello, I have a bit of the same problem, I am using the emulator suite for functions and firestore , but I can't set a task, I am getting error 4 ( i don't have access to the log yet I will update) . Do I need to setup the credentials for the client; or I need to use the emulator @ottob uses? Thanks

I fixed this by making sure that @grpc/grpc-js matched the exakt same version as google-gaxs dependency, which I found out by inspecting the yarn.lock file to be 1.1.8.

Simply running yarn add @grpc/grpc-js@1.1.8 was enough.

After that, it worked fine. You can also look in node_modules/google-gax/node_modules/@grpc/grpc-js/package.json to see which version you need.

I too am getting this error @ottob. I'll post here if I figure it out:

const client = new CloudTasksClient({ apiEndpoint: 'localhost', port: 8123 });

You should not use apiEndpoint. Just use it as follows:

const client = isLocalEmulator
  ? new CloudTasksClient({
      servicePath: 'localhost',
      port: 9090,
      sslCreds: credentials.createInsecure()
    })
  : new CloudTasksClient();

Use the correct port for your use case.

You also need to make sure you are using the same version of grpcjs across your project, Please look at my comment #462 (comment) above.
You can also use a resolution in your package.json file to force the version to the same one.

Thanks @AlexanderArvidsson! I totally missed the sslCreds: credentials.createInsecure() part from the original post. This now works great. The grpcjs version was correctly installed originally when I installed this library, and it's now submitting my tasks.

I verified it worked originally with the sample Python code, which had good documentation on how to send insecure GRPC calls, but the docs for the nodejs library are a bit lacking in that area. I'm glad I re-read your post and the original one to glean what I need to do to get it working.

Much appreciated, cheers!
