I just created the sign up/log in page, and it was working. Then all of a sudden the sign up stopped working. Everything else was working, the button was registering that it was being pressed, you can log in, log out, and everything but sign up.

I have made sure to import everything. I even got a past version of the code, when it 100% worked, but still didn’t work. No errors being thrown, nothing. Any Ideas?

Code:

 signUps.addEventListener("click", (event) => {


  var username = document.getElementById("username").value;
  var email = document.getElementById("email").value;
  var password = document.getElementById("password").value;
  if(validateInput(email) == false || validatePass(password) == false){
      alert("NOT ALLOWED");
      return;
  }

   const user = userCredential.user;
 createUserWithEmailAndPassword(auth, email, password)
  .then((userCredential) => {
// Signed up 
set(ref(database, 'users/' + user.uid), {
    username: username,
    email: email,
    last_login: Date.now()
});

alert("USER CREWAWERSDF");
  })
  .catch((error) => {
const errorCode = error.code;
const errorMessage = error.message;
alert(errorMessage);
// ..
  });
});
