Python error in chained Analytic Apps

[smarapad]

Hello,

I have 8 analytic apps, chained to run one after the other. 
All 8 apps use a Python tool. When I run them as analytic apps, I sometimes get the below error. The error does not appear when I do a regular run and also, it appears sometimes when run as an app but sometimes it just runs through with no error. When it occasionally runs as an app, there were no changes that went in. 

Any thoughts as to what is causing this?

Within the Python tool you will notice two modes,

Interactive and Production, is your workflow set to Production?

[smarapad]

It works when set to production mode.

Thanks Marie 🙂
