Hello,

It seems that the PR #44098 unfortunately breaks the onboarding process:

DEBUG: findPr(renovate/configure, undefined, open) (repository=xxxx)
DEBUG: Filling in onboarding PR template (repository=xxxx)
ERROR: Repository has unknown error (repository=xxxx)
       "err": {"message": "Cannot read properties of undefined (reading 'homepage')"}
       TypeError: Cannot read properties of undefined (reading 'homepage')

           at instrument.attributes (file:///usr/local/renovate/lib/workers/global/index.ts:235:11)
           at start (file:///usr/local/renovate/lib/workers/global/index.ts:220:7)
           at file:///usr/local/renovate/lib/renovate.ts:26:22

After some investing, I saw that the productLinks default configuration is missing starting from 43.232.1 (see the attached logs). Unfortunately, this is my first time using renovate and I'm afraid I lack experience to help further in the investigation on my own, I hope this will help the troubleshooting though.
