Prometheus endpoint returning invalid ARRAY(XXX) metrics

[freelock]

Hi,

Thank you for maintaining a current BackupPC image!

We have been using it for about a month for our servers. We initially switched over to it when we started using the Prometheus endpoint (/BackupPC_Admin?action=metrics&format=prometheus) -- with our own image we were hitting this issue: backuppc/backuppc#434 ... but your image worked, until today. Was the previous version just an older release? I'm wondering what changed in this most recent release that broke our metrics...

Cheers,
John

I am surprised honestly. The only real thing that is changing since the previous version is the Alpine base image, but nothing about BackupPC itself. So I guess the issue is with the perl runtime ...
