Firebase – Cloud firestore unable to deploy delete user function from project

Error: "Cloud Fire Error: functions predeploy error: Command terminated with non-zero exit code 1"

I have a view all users screen in my application. On this screen, I have access to both email and uID. I need to build functionality that I can click a delete user button on the users tile. This should then delete the user from firebase authentication and the users collection in firebase. I seen from other posts that the best way for this would be to create a cloud function which I have tried from firestore documentation. I am getting the below error. The code I am trying is from firestore documentation and is as follows:

getAuth()
  .deleteUser(uid)
  .then(() => {
    console.log('Successfully deleted user');
  })
  .catch((error) => {
    console.log('Error deleting user:', error);
  });

Any advice is much appreciated.

    Edit upon reading your question again:

    This isn’t a direct answer to your question but just a few things to note…

    You essentially have 2 options here – deleting the user form the front end or firebase functions – each is slightly different.

    Front end – You need to pass the user object into deleteUser() not the user’s uid, and vice versa passing in the uid.

    Firebase function example:

      return admin.auth().getUserByEmail(data.email).then(user => {
    return admin.auth().deleteUser(user.uid);
  }).then(() => {
    return {
      massage: `Success, ${data.email} has been deleted.`
    }
  }).catch(err => {
    return err;
  });

    Front end example:

    import { getAuth, deleteUser } from "firebase/auth";

const auth = getAuth();
const user = auth.getUser(uid)

deleteUser(user).then(() => {
  // User deleted.
}).catch((error) => {
  // An error ocurred
  // ...
});

    This may happen because:

    • You don’t have eslint installed. This could happen if at the time you ran firebase init functions you answered no when prompted Do you want to use ESLint to catch probable bugs and enforce style? and/or you answered no when prompted to install dependencies. If that’s the case reinitialize the environment to get it installed.
    • You’re missing the eslint package in your package.js file. To check/fix this open it up and look if you have something in the lines of:
    "devDependencies": {
    "eslint": "^4.12.0",
    "eslint-plugin-promise": "^3.6.0"
  },
    • As stated by @Werner7, that is also a possible solution.
