'Firebase error. Please ensure that you have the URL of your Firebase Realtime Database instance configured correctly.' Error

[Vlado202]

I installed Firebase via NPM to my project, initialized everything properly (created the 'sign up' and 'login' HTML forms, linked all the elements to my script.js file where initialized the basic imports and setup for a Firebase app, and added additional functionality), and judging by the analytics on the Firebase dashboard, I can see that the app is working, but when I try to interact with it (run it on my server and test the functions), it displays the following error:

"Firebase error. Please ensure that you have the URL of your Firebase Realtime Database instance configured correctly."

Anyone know what I can try to resolve this issue?

Can you share your initialize code?

Here is the code for the entire Sign Up / Login feature.

I removed some information from the 'const firebaseConfig', since I'm not sure if it is sensitive or not, but it was all copied straight from my Firebase project, so I don't see the issue being related to that.

There were changes where the databaseURL is not auto-generated. You can add the databaseUrl to the firebaseConfig to fix it

const firebaseConfig = {
    apiKey: "/",
    authDomain: "/",
    projectId: "/",
    storageBucket: "/",
    messagingSenderId: "/",
    appId: "/",
    measurementId: "/",

    databaseURL: `https://YOUR_PROJECT_ID.firebaseio.com`,

};

It sadly did not fix the issue.
