the url path needs to be updated to append /t5/s to hit those legacy REST endpoints.
Okay, that could solve it, thanks! I'll relay it back to the team for a temporary fix, and then we can work on updating them to GraphQL properly.
The other thing to check with be how they are authenticating. Most likley they are doing a proper auth flow, but classic also allowed the session id cookie to be used for API auth which was not recommended but possible in older instances of classic. To further protect the API and data, Aurora does not allow this to be used to authenticate APIs requests.
