How to Resolve Cross-Origin Read Blocking (CORB) blocked cross-origin response and Cross Origin errors while calling api from axios ,I am getting CORS ERROR please check the above code

You can either solve this in the backend using an NPM package called CORS. Or you can use the chrome extension "Allow CORS" for a temporary solution. — Kevin.a, Jan 07 '20 at 15:01

If you have control of the nodejs server, you could use the next middleware after installing it with npm install cors

var cors = require('cors');
app.use(cors());

I was assuming he has control. I agree with you. Edited. – fjplaurr Jan 07 '20 at 15:06
I don't have backend access, am using react js for calling the api – htyagi1 Jan 08 '20 at 07:06
