Server version 6.15.12.23  
Studio version 6.15.10.15

Running in browser worked fine, but when running on Zebra, flow returned this error when starting the flow.

I had changed the flow, the update was limited to a single task, a SQL query, to fetch data.

Looking for help on how to fix, and what caused the problem in the first place.

Hi @oscarxyz,  
Do you have the latest version of the flow app installed in the Zebra device?  
Thanks
