I am using Azure Functions to host apis and Angular as front end. I am facing issues with Chrome PreFlight [OPTIONS] request which gets 400 Bad request Error.

Screenshot of Request in Chome

It works on my Dev Machine. I do not see any pre flight errors.

Have you added the host where angular front end locates to CORS list?

On more digging I found that when I add Authorization bearer token in the header I get this error...

You need to go to Platform Features tab -> Click on CORS and add your FrontEnd URL to the list of Allowed Origins.

If you add * to CORS list you have to remove all the other URLs. Otherwise neither of them are applicable
