App Platform: Could there be a "allow_headers" option for CORS?

Hey there.

I am getting the CORS error: “Request header field authorization is not allowed by Access-Control-Allow-Headers in preflight response.”

This is due to not being able to set “allow_headers” in the App Specification file. (This key does not yet exist.)

Is there any way to do something about this?

Stay healthy! Nick

You can actually do it by download the yaml file and adding it manually.

    - '*'
    - GET
