431 (Request Header Fields Too Large)

Question

GET http://localhost:3000/data/posts.json 431 (Request Header Fields Too Large) I am getting an error mentioned above. I am using local server "npm server" (No Xampp or WAMP)

JSON file is downloaded from here "https://gorest.co.in/public-api/users?_format=json&access-token=UrX-V34IN7O-1TV0HEaVUCRUz65B9-ibL6M1" I have downloaded this file on local server.

My Code is:

const API = './data/posts.json';

componentDidMount(){

        fetch(API)
        .then(response => response.text())
        .then( (data) => { console.log("data - ", data) } )
    }

3-go to "privacy and security" section

4-click on site settings

5-click "view permissions and data stored across sites"

6-find localhost and on the right menu reset data
