All Apps and Add-ons

After installing Splunk Add-on Builder, why do I receive error "Unable to initialize modular input "validation_mi""?

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

Clicking on Splunk Add-on Builder opens a blank page > receive above message

hi all,

I'm getting error same error after installing the Splunk add-on builder(2.2.0) on Splunk 6.5. What could be the issue. I know if it is 3.0 then it won't work on Splunk < 8 version. I have python 2.3. Please help me with this.

Hey @harig86 
I suggest you to extract the package using 7zip and put it under $SPLUNK_HOME/etc/apps/
Then splunk restart.  It would work fine without any error. 
I suspect that it would kindoff read permission issue in package.

Hi All-
Here is what I found in my experience:
The add-on builder 3.0.0 and 3.0.1 will NOT work for anything less than Splunk 8.0.0.

Please note! This is my experience and YMMV

Only use 2.2.0 with Splunk Enterprise <8.0.0 (example, I am successfully using TA-AddOnBuilder with Splunk ENT 7.2.7)

Hope this helps someone,

This has resolved the issue for me. Thank you

Is now also an issue for me after upgrading to Version 3.0.0.
