[cloud_functions] Unauthenticated error on .call()

[ishtms]

I am trying to call a Callable function using the cloud_functions package. I've tried using the example code as well and still getting the same error -

PlatformException(functionsError, Cloud function failed with exception., {code: UNAUTHENTICATED, details: null, message: UNAUTHENTICATED})

The firebase app is on spark plan (Just in case if that matters?). I've tried using Node version 8 and 10, but no luck.

The dart code -

CloudFunctions(region: 'asia-east2').getHttpsCallable(functionName: 'addUser').call({ "name": "Test", "email": "abc@example.com" })

Callable function's code -

exports.addUser = functions.region('asia-east2').https.onCall((data, context) => { const users = admin.firestore().collection('users'); return users.add({ name: data["name"], email: data["email"] }); });

Hi @Ishtmeet-Singh
can you please provide your flutter run --verbose from root of your project?
Thank you

I am using VS Code's flutter extension to run the project.

What version of the Firebase CLI are you uploading the functions with?

See this page: https://firebase.google.com/docs/functions/callable :

@Ehesp Thank you very much. I was using 7.3.1. Upgrading solved the issue for me.
