What did you do that produced an error?

I generate the snmp.yml like i generate for zyxel. For zyxel 0 issues. I use MIB Browser with the MIB file and i have metrics

What did you expect to see?

Metrics in prometheus and grafana

What did you see instead?

expected a valid start token, got "<" ("INVALID") while parsing: "<" in prometheus for iDRAC and Synology

I think it's because I'm using one module per target, when I test a single module for all targets it works.
The prometheus config :
