Unable to initialize modular input "validation_mi"

Splunk Search

I'm unable to use the Validate & Package function of Add-on builder. When I run it, it says 'preparing validation' then nothing, empty white results. All I can do is press the validate button again with the same result. I've tried with other apps in the Add-on builder with same results.

I have a local instance of Splunk Enterprise running. Fresh install so v8.2.2 and App-builder is on 4.0.0.

I did catch a notification in messages:

Unable to initialize modular input "validation_mi" defined in the app "splunk_app_addon-builder": Introspecting scheme=validation_mi: script running failed (exited with code 1)..

Don't know what this means or how to fix it. Any ideas?
