Can't debug a Extension Section, "Make sure the steps are compatible with the current attributes and variables values."

[Fredric Melcher]

Hello, 
I'm very new to ServiceNow discovery and trying to learn here. 🙂 

I've tried to create an extension section under the pattern "Windows OS - Desktop" and whatever step I add, i get this:
"Test failed: Make sure the steps are compatible with the current attributes and variables values."

If I run a discovery with the pattern it fails at the last step with:
"Identification Engine: Discovery status is FAILURE, Discovery using patterns failed due to lack of existence of the main CI type in the results. Check the discovery logs for more details."

Even if I only create a variable in 1 step, it still fails. I've looked at some youtube videos and read a lot online, all guides on extension section is really simple and easy. What am I doing wrong?

Thanks!

When I check the discovery log, I find: 

"Failed Exploring CI Pattern, Pattern name: Network Routing Device - Light, To Check Pattern Log"

and inside that:

"
Identification Engine: Discovery status is FAILURE, Identification sections in pattern failed: section: discovery, error: Failed to establish SNMP connection to host (our router)
"

It's the only Error that I can find...

HI,

So on this device on network are the ports open and also SNMP configured. Also check Access control list on this device.

Thanks,
