FirebaseError: Firebase: Error (auth/invalid-email)

I am making a react project and when I am trying to sign up through email and password using firebase authentication then this 👇your text error is showing
This is the error I am getting
This is the whole code:
import React,{useState} from 'react';
import { Link, useNavigate } from 'react-router-dom';
import Layout from '../components/layout/Layout';
import {BsFillEyeFill} from "react-icons/bs";
import { getAuth, createUserWithEmailAndPassword , updateProfile} from "firebase/auth";
import {db} from "../firebase.config"
const SignUp = () => {
// to hide password
const [showPassword, setShowPassword] = useState(false);
const [formData, setFormData] = useState({
email:"",
name: "",
password: "",
})
const {name, email, password} = formData;
const navigate = useNavigate();
const onChange = (e) => {
setFormData((prevState) => ({
...prevState,
[e.target.id]: e.target.value,
}));
};
This is my signUp function
const onSubmitHandler= async (e) =>{
e.preventDefault();
try{
const auth= getAuth()
const userCredential = await createUserWithEmailAndPassword(auth,email,password);
const user = userCredential.user
updateProfile(auth.currentUser,{displayName: name})
navigate("/")
alert("Signup Success")
}catch(error){
console.log(error);
}
}
return (

export default SignUp
After going through firebase documentation I have tried various emails but still it is showing the same error.
This is the email I had been using for signUp.
and I tried different emails as well like: piyush#gmail.com, and my personal email too but still it is showing the same error

This is the error message for your error
auth/invalid-email:
The provided value for the email user property is invalid. It must be a string email address.
Check to make sure your onSubmitHandler is within scope of your formData state, because your email and password might be undefined.

Your code has 2 issues,
1: Check the spelling of onChange on email and password field.
2: Change defaultValue to value
Below is the working code:
import React, { useState } from 'react';
import { Link, useNavigate } from 'react-router-dom';
import { BsFillEyeFill } from 'react-icons/bs';
import {
getAuth,
createUserWithEmailAndPassword,
updateProfile,
} from 'firebase/auth';
const Signup = () => {
const [showPassword, setShowPassword] = useState(false);
const [formData, setFormData] = useState({
email: '',
name: '',
password: '',
});
const { name, email, password } = formData;
const navigate = useNavigate();
const onChange = (e: any) => {
setFormData((prevState) => ({
...prevState,
[e.target.id]: e.target.value,
}));
};
const onSubmitHandler = async (e) => {
e.preventDefault();
console.log('email is ', email, password);
try {
const auth = getAuth();
const userCredential = await createUserWithEmailAndPassword(
auth,
email,
password,
);
const user = userCredential.user;
alert('Signup Success');
} catch (error) {
console.log(error);
}

Modal pop up on submit in React

I am trying to display a modal pop up on submit in a form in React. Right now, the invalid email and name modal pops up just fine. The problem is, It will not display the alternate success message if the form was submitted correctly. I also am not sure if it will persist upon successful submission, but can't get past this problem to test it out. Please let me know where I am going wrong. Thanks!!
Contact.js:

const Contact = (props) => {

const [enteredEmail, setEnteredEmail] = useState("");
const contactHandler = (event) => {
event.preventDefault();
if (enteredName.trim().length === 0 || enteredEmail.trim().length === 0) {
setShowModal({
title: "Invalid Input",
message: "Please enter a valid name and email",
});
return;
}
if (enteredName.trim().length > 0 || enteredEmail.trim().length > 0) {
setShowModal({
title: "Thank You",
message: "Your form as been submitted",
});
return;
}
props.Contact(enteredName, enteredEmail);
setEnteredName("");
setEnteredEmail("");
};
const modalHandler = () => {
setShowModal(null);

*disclaimer : my grammar so bad so i am apologize about that.
i just try your code and when i submit is always invalid, i check it and the state name and email is empty string when i submit because your forgot implement onChangeHanlde in input.
create function to handle onChange
const onChangeHandler = (field, event) => {
if (field == "email") {
setEnteredEmail(event.target.value);
} else if (field == "name") {
setEnteredName(event.target.value);
}
};
and add onChange, value attribute in input tag both name and email
<input
className="form-bg p-2"
type="text"
placeholder="Name"
name="name"
onChange={(e) => {
onChangeHandler("name", e);
}}
value={enteredName}
/>
<input
className="my-4 py-2 form-bg"
type="email"
placeholder="Email"
name="email"
onChange={(e) => {
onChangeHandler("email", e);
}}
value={enteredEmail}
/>

You didn't put
value = {enteredName}
in your input element. so your states will not be set by user's input.

is this a result of firestore latency or normal behavior

I have a form I am using to allow users to add comments to my site. The form has an input field, a textarea field, and a button. When the button is clicked it runs my addComment() function which adds the name, comment, and timestamp to my firestore collection as a new doc.
It seems like after I click the button to add a comment I have to wait a few seconds before I can post another one. If I try to add a new comment too quickly then request doesn't get sent to my firestore collection, but if I wait a few seconds everything works as expected.
I am curious if this is normal behavior? How can I set it up so users can always post comments without having to wait a few seconds? Can someone explain to me what is happening?
Thanks
Update:
I have been doing some debugging, and I have noticed that both of the functions getVisitorCount() and getUserComments() from the first useEffect run every time I type something into the name or comment input boxes. I have attached screenshots to showcase what is happening.
On the first initial load of the app:
After typing something in the name input box:
Finally, typing something into the comment box as well:
This is not the desired behavior I want these two functions should not be running when I am typing something into either text field. The getUserComments function should only run on the initial render of the app, and whenever the add comment button is clicked.
Could this be what is causing the problems I am experiencing?

But When AT Node server End All Other filed Is recieved as Empty Except image Data
OUTPUT OF DATA SAVED IN DATABASE
And If I follow the Approach in Which I use Simple Object as the data instead of form Data(), I and with header ( that are under // ) I do not receive images at the backend and only receive user info

One solution could be to send the image as a string (base64) to the backend to save the image.
try to implement this in your react:
import { useState } from "react";
import "./styles.css";
export default function App() {
const [img, setImg] = useState("Image string will come here");
const handleChangeImg = (e) => {
console.log(e.target.files[0]);
const reader = new FileReader();
reader.readAsDataURL(e.target.files[0]);
reader.onloadend = () => {
setImg(reader.result);
};
};
return (
<div className="App">
<h1>Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
<input onChange={handleChangeImg} type="file" name="image" />
<button onClick={()=>setImg("Image string will come here")}>Reset</button>
<h1>{img}</h1>
</div>
);
}
Check the code iin codesandbox here.

setting the value of more than one input

I am trying to build a login form. I am trying to set up the value of the email & password field individually. But as soon as I try to enter the text in the email text field, the same appears in the password field too. Can I have a solution to this?
Below is the code.
I guess the error is in OnChange fn where I am assigning the same value e.target.value to both the {email, passwaord}.
import React, { useState } from "react";
import { useNavigate } from "react-router-dom";
const LoginPage = () => {
let navigate = useNavigate();
const [credentials, setCredentials] = useState({email:"",password:""});
const onChange = (e) => {
setCredentials({email: e.target.value ,password: e.target.value})
console.log(credentials.email, credentials.password)
}
const goToSignUp = () => {
navigate("/signup");
}

export default LoginPage;

You have identified the problem. You need to pass the key to change as well.
Here passing a callback to setState which provides the current state as a parameter, cloning the state object using spread syntax, and then updating the relevant property in the copied object using the passed key as a computed property name.
const LoginPage = () => {
const [credentials, setCredentials] = useState({email:"",password:""});
const onChange = (e, key) => {
setCredentials(prevCredentials => ({...prevCredentials, [key]: e.target.value}))
}
return (
<>
//...
<input
type="email"
className="form-control"
id="email"
name="email"
value={credentials.email}
aria-describedby="emailHelp"
onChange={(e) => onChange(e, 'email')}
/>
//...
<input
type="password"
className="form-control"
id="password"
name="password"
value={credentials.password}
onChange={(e) => onChange(e, 'password')}
/>
//...
</>
);
};
Note: Calling console.log() right after setting state will not log the updated state, the new state values won't be available until the next render cycle. see: useState set method not reflecting change immediately

Use the proper key to the respective fields
const onChange = (e) => {
setCredentials({ ...credentials, [e.target.name]: e.target.value})
console.log(credentials);
}
