I am trying to account link using our companies OAUTH2 Server. When I try and test oauth using the postman redirect uri, it works, but when i try and link with amazon, I am having issues.
When amazon calls the authorization endpoint, all is well, I log in, grant permission, but when it redirects to https://layla.amazon.com/api/skill/link/xxxx?code=xxxx&session_state=xxxx, or the pitangui one, i receive a 500 Internal Server error response code with the body being "{"message":null}"
Anyone able to help me figure out what is going on
