Yes. Instructions were followed as well as deleting ~/perl5 just in case.
One more error as well since last time which does not include a timestamp
for some reason. Here's the errors since last backend startup:

Hi there
I had set up a new ND2 host on debian buster some weeks ago
for experimental purpose
I have another ND2 host up and running since years
Software Version
App::Netdisco 2.44.4
SNMP::Info 3.70
DB Schema 61
PostgreSQL 12.00.1
Perl 5.28.1
I restore db from another ND2
and copy deployment.yml
It worked
But I noticed that it stops running the scheduled jobs after some times (days)
I had to restart netdisco-backend,
here some info I collect
from netdisco-backend.log
...
