/metrics endpoint crashes Bodhi on F41

[mattiaverga]

This only happens on F41, F40 seems fine (for now):

@AdamSaleh you originally wrote the prometheus endpoint, any idea on what's going on? I see prometheus-client has been upgraded to 0.21 on F41, while it's still 0.20 on F40. Do you think it's the culprit?
