Axios: Axios sends an OPTIONS (http code-204) request before/ after every get request.

Summary

Hi I am using axios with react, and I am facing a strange issue. After every get request, the axios library makes a 204 request. Is it supposed to be this way, or am I doing something incorrectly ? Here is the required stack trace from the backend.

Axios isn't making those requests, the browser is. Please take a look at CORS.
