      How to Reproduce

      • Setup Multibranch and include PR from forks
      • Create a PR from a fork
      • Delete the Fork
      • Run the scan

      It fails with the above exception.

      Further Information

      Here is an example payload for the source from Bitbucket cloud:

      [...]
                  "source": {
                      "branch": {
                          "name": "branch-from-fork"
                      },
                      "commit": null,
                      "repository": null
                  },
      [...]
      

      Workaround

      Decline the PR and scan again.
