New to vue/firebase. I was able to lookup how to pull up “current user” data from auth no problem but trying to write a js composable that I can pass in any user id (not necessarily current user) and it will return the user object or at least displayName.

All the docs/vids I can find on the topic reference getting info on *current user *only not another user. From the Google Docs it says I should be able to do this in the "Retrieve user data" section. Closest model to Vue code-wise seems to be “Node.Js” but it isn't working.

Here's what I've got in getUserById

import { getAuth } from 'firebase/auth'

const getUserById = (u) => { // u = user id
    const userData = null
    getAuth()
        .getUser(u)
        .then((userRecord) => {
            // See the UserRecord reference doc for the contents of userRecord.
            console.log(`Successfully fetched user data: ${userRecord.toJSON()}`);
            userData = userRecord
        })
        .catch((error) => {
            console.log('Error fetching user data:', error);
        });

    return { userData }
}
export default getUserById

The error I get is getUser is not a function. I tried adding getUser to the import but same error.
