Basically Drone is not able to activate repos in a subgroup of repositories
For instance https://gitlab.com/alexandro/isss/data-monitoring/
username: alexandro
group of repo: isss
repository name: data-monitoring
I get this kind of errors from my drone server container
{"admin":false,"error":"404 Project Not Found","level":"warning","msg":"api: cannot sync repository permissions","name":"data-monitoring","namespace":"isss","read":true,"request-id":"1Sexxxxxxxxxxxxxxxxxxx","time":"2019-10-24T17:38:56+02:00","user.admin":true,"user.login":"admin","write":false}
I should clarify than I can activate projects without a level like this without any issue: https://gitlab.com/alexandro/drone-playground/
