Linux CI identification issue

[johnantony26683]

Hi all, 

While running discovery of 5 Linux CIs, 2 of them are not getting discovered and I've attached the payload error. It's happening at the identification stage, as seen on the snippet attached. 
It is using the identify rule for the table dscy_route_interface, which is network related and not Linux/Unix related. 
Any help would be greatly appreciated.

That's the hardware rule. Which is getting inherited in the linux server table. Attaching screenshot check 400 one. If you are not getting the value in the payload then try checking the box accept null value for trial.
