How to resolve unspecific HACs errors?

All of the sudden, I have the following error in my hassio:

Setup failed for hacs: integration not found.
Logger: homeassistant.setup
First occurred: 10:31:57 AM (1 occurrences)
Last logged: 10:31:57 AM

How can I find out how to resolve it?
I mean, there are no other failures in logs that I could make use of.

Could fix it reinstalling HACS completely…
