Question

Guys, I had installed a truemail on a GCP CloudRun. It runs and answer right when I send requests using Insomnia (like Postman).

However, when I send calls from my web application I receive a CORS block message:

Access to XMLHttpRequest at 'https://truemail.XXXXXX/?email=XXXXXX' from origin 'http://XXXXXX' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

My ajax request uses 'crossDomain' parameter and headers 'Access-Control-Allow-Origin': '*', but I guess I need to enable CORS requests in TrueMail.

Would you like to help me?
