Modular input error on defender-atp-hunting

[dyeyniyel]

I'm getting below error for the TA-defender-atp-hunting on our HF.

Unable to initialize modular input "defender_hunting_query" defined in the app "TA-defender-atp-hunting": Introspecting scheme=defender_hunting_query: script running failed (exited with code 1)..

I'm not able to access the defender atp hunting app via UI. Would anyone know how to resolve this issue? 

Thanks in advance!
