firebase_auth/captcha-check-failed

signInWithPhoneNumber method works fine for web platform.
signInWithPhoneNumber method for desktop (macos, windows) only works with test phone number and verification code.

But it does not work with any real phone numbers. This error shows up when any real phone number is provided.

[firebase_auth/captcha-check-failed] The reCAPTCHA response token was invalid, expired, or is called from a non-whitelisted domain.

How can I solve this issue?

Go to Authentication > Sign-in method > Authorized domains, then add 127.0.0.1 to the list of authorized domains in Firebase Console.
