Struggling to detect mistakes utilizing the createUserWithEmailAndPassword() function in Firebase

My attempts to debug the issue have been unsuccessful, resulting in my code not identifying errors like creating a user with an email that is already registered. While it does provide a response, it's not the one I anticipated such as firebase/email-in-use. The console displays an error with undefined. Here is the snippet of code:

import { createUserWithEmailAndPassword } from "firebase/auth"
import { auth } from "../../../firebase/config"

export default function Content() {
   const emailSignIn = async () =>{
      try{
        createUserWithEmailAndPassword(auth, email, password)
      }catch(error){
        console.log(error)
      }
    }
    return (
    <div className="h-[5vh]">
      <input type="text" placeholder="Email address" onChange={(e)=> setEmail(e.target.value)}     className="w-full border-2 h-[4vh] border-[#e4ebe4] rounded-2xl font-normal text-base p-3 pl-5"/>
    </div>
    <div className="h-[5vh]">
       <input type="text"
    placeholder="Password (8 or more characters)" onChange={(e)=> setPassword(e.target.value)} className="w-      full border-2 h-[4vh] border-[#e4ebe4]  rounded-2xl font-normal text-base p-3 pl-5"/>
    </div>

The console error message reads:-

app-index.js:31 undefined
window.console.error @ app-index.js:31
console.error @ hydration-error-info.js:45
emailSignIn @ content.js:24
callCallback @ react-dom.development.js:19443

I have attempted to access the error.code and error.message properties without success. Additionally, I tried utilizing firebase functions to check if a user with the email already exists but encountered difficulties with the .then structure and async function behavior in JavaScript. This project is developed using next.js version 13.

Think of the createUserWithEmailAndPassword() method in Firebase as a JavaScript promise

Instead of using:

try{
   createUserWithEmailAndPassword(auth, email, password)
}catch(error){
   console.log(error)
}

Consider using this instead:

createUserWithEmailAndPassword(auth, email, password)
  .then((userCredential) => {
    // User successfully signed in
    const user = userCredential.user;
    // ...
  })
  .catch((error) => {
    console.log(error);
    // Handle errors here
  });
