Newly Created Firebase Functions Throwing UNAUTHENTICATED Error

Question

I have a Firebase project with over 10 cloud functions. Today I added 3 more, but all three of the new ones are throwing an error UNAUTHENTICATED without actually trying to hit the function. (There's no record of a function call in the logs). I haven't made any changes to my environment or Firebase project since adding the previous functions.

I have tried redeploying all of the functions in my project, the three newest ones continue to fail while the previous ones work fine. I have also verified that I am using Node 8, since there are some similar issues reported stemming from using Node 10. I am not sure what else to try since the issue only applies to the new functions.

The new functions all have a similar signature:

exports.createGroup = functions.https.onCall((data, context) => {
  //Firestore access
});

They are being called like this:

const create = functions().httpsCallable('createGroup');
return create({ group: oGroup }).then(result => {
      //Do something
}).catch(err => {
      console.log(err.message); //UNAUTHENTICATED
});

Node Version: 8.16.2

Firebase Tools Version: 7.6.1

I've disabled "Cloud Scheduler API" and then reenabled it. After that it started working. — Hemant Kaushik

It must be solved at your GCP Console (not Firebase). Just follow these steps:

Go to your GCP Console and login
On the top menu, select the corresponding Firebase project
On the left menu go to Cloud Functions Click the checkbox of your function (not the name of the function)
Once selected, on the right menu select "Add member"
On "New member" type allUsers
On the Select function bar, select Cloud Functions -> Cloud functions invoker
Click on "Save" and then "Allow public access" on the pop-up warning And you're good to go!
