So, I've looked online for information about this error and I haven't found great results. The error is "You have found a bug. The pipe has been ended". I found a few discussion post about this but the most common response is to turn off the AMP engine. However, I have a workflow is absolutely reliant on control containers so I can't turn off the AMP engine. Then I saw a suggestion to copy it to new workflow and that didn't work either. It only happens when I run my workflow through the batch macro when I run the macro body on it's own it doesn't ever cause this error. I am not containing to any databases or anything only .CSV files. Any advice before I contact Alteryx support?
