Python tool in combination with CReW list runner

5 - Atom

Hi All,


I use the CReW list runner to run a number of Alteryx workflows every day. Some of these workflows contain the python tool, which has started giving errors since we upgraded to Alteryx 2019.2. If the Alteryx flow contains a python tool and is run through the list runner, I get the error "Internal Error: Unknown InitVar "IsDebugAnalyticApp". If I just run the workflow directly, everything works fine. Does anyone recognize this error? If yes, do you know how to resolve it?

Any workaround on this, we were stuck in the prod release due to this bug.

Moment we use crew macro it fails, individually it runs.


I think we need a priority fix. Please check and let us know.

Not a good workaround but I was able to have my main workflow that contains all my python code and use a "block until end" to order what needs to run first. So I remove python code from my subworkflow.


It worked for me but I agree with you and would like to see a fix!

Hi, something new?

@juandiegocuervo  I think the bug is still not fixed. So workaround is the only option.

Hi @MichaelAd, do you have any updates on this? 


All the best,

+ 1 for a fix on this.  I use python a lot.  I use Crew runners a lot.  We need peanut butter and jelly!

Does anybody know if this issue has been solved? I'm facing the same problem!

It has not been solved. 

One good workaround is to use a run command tool to call a .py file, or the event tab to do the same.
