Improve feedback for missing permissions on GitLab

Tell us more.

When renovate is missing permissions for a repository the output in the logs is similar to

DEBUG: Autodiscovering GitLab repositories
DEBUG: hostRules: applying Bearer authentication for gitlab.com
DEBUG: Discovered 6 project(s)
DEBUG: Autodiscovered 6 repositories
DEBUG: Applying autodiscoverFilter
       "autodiscoverFilter": "[...]"
DEBUG: None of the discovered repositories matched the filter

when all repos are unter myorg/. Users usually start with a complex filter to try renovate in a subgroup. I then hit this error and started to trial and error regex modifications until I finally narrowed it down to myorg/* and finally omitting autodiscoveryFilter.

Through a stroke of luck I figured out that the issue has nothing to do with the repositories not being found, but that it must have been the GitLab Group Access token sitting too low on the group hierarchy, thus not having permissions to read the repos.

After moving it up, I could discover all repositories and use the filter as intended, but the 4 hours until then are lost. Very helpful would have been: 6 of the discovered 6 repositories matched the filter, but the GitLab Access Token is lacking permission for them.

renovate/lib/workers/global/autodiscover.ts

Line 47 in ea4469a

logger.debug('No repositories were autodiscovered');

if you see this message, then the platform didn't return any repo. filter is applied later

renovate/lib/workers/global/autodiscover.ts

Line 62 in ea4469a

logger.debug('None of the discovered repositories matched the filter');

you should run with debug log level when starting on renovate or changing settings.
