Facebook test user

Is there anyone who uses OAuth for website user login like me? There is a "test user" on the Facebook developer page. It can be used to test whether the function of Facebook is normal, Because when the website moved to Google’s GCE, for some reason, I actually posted one more in the $fillable array of Laravel’s User model~, Normally the program works fine, but when a new user logs in, an error is shown to you. I keep hearing people say that I can't log in to this website to leave a message. I want to say that I am very normal. @@ After using the test user test today, ha, I found that the login function on my website has been broken for a long time.
