Hello!
Thanks in advance for helping me figure this out. I can not get my head wrapped around why the optional output or input field are clearly marked as optional but the output of the Run Command generating the error below. Others on the team have noticed the same issue and were wondering the same..
In the screenshot below, this is batch file that changes the file name (and no, due to design/process issue, it can not be done in Alteryx)
How could that be and what is the logic behind it? Or what am I missing?
