Azure APIM Developer Portal - Need help with handling CORS errors

Hari Prathipati 0

Hello,

I'm trying to test an API operation, but when I provide an invalid subscription key, the error message returned is related to CORS rather than an invalid subscription error message. However, I receive a success response when using a valid subscription key. Can someone please help me figure out how to properly handle these CORS errors so I can receive the correct response message?

Thanks in advance.

Regards, Hari
