I was trying to fix this error I was facing:

"Refused to execute a script because its hash, its nonce, or 'unsafe-inline' appears in neither the script-src directive nor the default-src directive of the Content Security Policy."

I'm trying to make a contact us page and its unable to POST.

import React, {useState,setState} from 'react';
import "./Contactus.css";
import axios from 'axios';

class Contactus extends React.Component{

  constructor(props) {
    super(props);
    this.state = {
      name: '',
      email: '',
      message: ''
    }
  }
  
   handleSubmit(e){
    e.preventDefault();
    axios({
      method: "POST",
      url:"http://localhost:3002/send",
      data:  this.state
    }).then((response)=>{
      if (response.data.status === 'success') {
        alert("Message Sent.");
        this.resetForm()
      } else if (response.data.status === 'fail') {
        alert("Message failed to send.")
      }
    })
  }

  resetForm(){
    this.setState({name: null, email: null, message: null})
  }
render() {
  return (
    <div className="contact-form-box">

      <h1> Contact Us</h1>
      <form id="contact-form" onSubmit={this.handleSubmit.bind(this)} method="POST">
    <div className="form-group">
        <label htmlFor="name">Name</label>
        <input type="text" className="form-control" />
    </div>
    <div className="form-group">
        <label htmlFor="exampleInputEmail1">Email address</label>
        <input type="email" className="form-control" aria-describedby="emailHelp" />
    </div>
    <div className="form-group">
        <label htmlFor="message">Message</label>
        <textarea className="form-control" rows="5"></textarea>
    </div>
    <button type="submit" className="btn btn-primary">Submit</button>
     </form>
    </div>
  );
}
onNameChange(event) {
  this.setState({name: event.target.value})
}

onEmailChange(event) {
  this.setState({email: event.target.value})
}

onMessageChange(event) {
  this.setState({message: event.target.value})
}

handleSubmit(event) {
}
}

export default Contactus; 

I have tried adding a META tag outlining the content security policy in the index.js file but it created more errors alongside the original ones
