Firebase auth twitter social login not works

[Larry Neil Mcgowen]

I am working on integrating Twitter login with firebase auth.
I referenced this doc: https://firebase.google.com/docs/auth/web/twitter-login
But I have an error in twitter login with firebase auth.
If I run this code when click on the signin button, 
```

const provider = new TwitterAuthProvider();

    signInWithPopup(auth, provider)

    .then ((result) => {})

    .catch((error) => {}) 

```
It opens a popup dialog and it shows me this kind of error.
Attached the error screenshot.

Let me share the project with you.

I am not sure what is wrong.

I am very appreciate for your help.
