Role not found - 404

Hi,

Ive tried everything that I could think of, but I am still getting this message when I call the email service via POST.

I setup an AWS SES email service, then Assigned Service Access to that Role. I have also assigned the role to the app.

Now when I use the API_DOCS the email is working fine, but when I use the POST method via POSTMAN etc it shows role not found. I have tried almost everything that I could think of, please help.

Thanks,
