Reason: Multiple CORS header ‘Access-Control-Allow-Origin’ not allowed

What went wrong?

More than one Access-Control-Allow-Origin header was sent by the server. This isn't allowed.

If you have access to the server you can change your implementation to echo back an origin in the Access-Control-Allow-Origin header. You cannot send back a list of origins, because browsers only accept a value that is either a single origin or null
