axios vue js - cross-origin request blocked the same origin policy disallows reading the remote resource

i'm new learn vue js, i want to send data API from vue JS to Backend Laravel. Data already sent to backend and already saved to database. But when i'm check console after send parameter, then vue js redirect to catch not response.

And this error in console => Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:2000/register/store. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

I don't know, why parameter has been received in backend and success, but vue js not redirect to response. So it doesn't display alert message :(

This respond from backend laravel :

{"message":"Success!","status":"200","value":"{\"nama\":\"test\",\"email\":\"test@gmail.com\",\"password\":\"123\",\"updated_at\":\"2020-05-07T05:50:41.000000Z\",\"created_at\":\"2020-05-07T05:50:41.000000Z\",\"id\":48}"}

And this my code

<template>
      <div id="app">
        <img alt="Vue logo" style="width:100px;height:100px" src="./assets/logo.png"><br/><br/>
