We have the following error in our stack trace :

We contacted the destination service that redirected us to you. NGPBUG-358871
I can't test the destination via HTTP call as It would require customer credentials.

The message:

Empty Body with status 302 and message Found comes from the OAuth Service!

... is an error reported by Destination Service, while it tried to resolve some OAuth token.

  • SAP Cloud SDK is only propagating the error message to you as exception.
  • Destination Service seems to not following 302 redirects. Maybe some destination property has not the correct URL.
  • Please make sure the OAuth2 server address is absolute correct, including domains, paths and especially schema (http vs. https). This is the Token Service URL in a destination.
