Hi All,

I'm trying to discover Linux server and Discovery completed in Classified phase. Linux pattern ended in Error and below is the error i see in logs. 

Identification Engine: Discovery status is FAILURE, Identification sections in pattern failed: section: discovery, error: JAVASCRIPT_CODE_FAILURE: TypeError: Cannot convert null to an object. (ad_hoc:EvalClosure-Filter route interfaces-705444873; line 11).

Identification Engine: Discovery status is FAILURE, Identification sections in pattern failed: section: discovery, error: JAVASCRIPT_CODE_FAILURE: TypeEr

Then you should open a case with support they will be able to assist with the update.

You need to check the pattern log and see which step has this null exception and debug the pattern to understand why it is happening. It must be definitely due to an eval script on that step.

If you are unaware of this troubleshooting, as Doug mentioned, you can raise a case with us.
