Reason: Did not find method in CORS header 'Access-Control-Allow-Methods'

The HTTP method being used by the CORS request is not included in the list of methods specified by the response's Access-Control-Allow-Methods header. This header specifies a comma-delineated list of the HTTP methods which may be used when using CORS to access the URL specified in the request; if the request is using any other method, this error occurs.

For example, if the response includes:

Access-Control-Allow-Methods: GET,HEAD,POST

Trying to use a PUT request will fail with this error.

Make sure your code only uses the permitted HTTP methods when accessing the service.
