CORS_PREFLIGHT_MAX_AGE: int. The method looks like that: Since the originating port 4200 is different than 8080,So before angular sends a create (PUT) request,it will send an OPTIONS request to the server to check what all methods and what all access-controls are in place. By default, in cross-origin XMLHttpRequest or Fetch invocations, browsers will not send credentials. If the client is a browser, there is a known issue with this plugin caused by a limitation of the CORS specification that doesnt allow to specify a custom Host header in a preflight OPTIONS request.

The Cross-Origin Resource Sharing standard works by adding new HTTP headers that let servers describe which origins are permitted to read that information from a web browser.
