Powershell Script Works Correctly in Alteryx Designer but not on Alteryx Gallery

[vivansai]

I asked this over on the Alteryx forums and unfortunately didn't 
get any answer. Hopefully someone here with Alteryx/PS experience 
will know the issue. I have a workflow that runs a batch file 
with a tabcmd command to export data from tableau into a csv in a 
share drive folder. Then a powershell script runs that reorders 
the columns, and moves them to another folder. Finally, a second 
powershell script runs, converts the csv to xlsx and exports that 
to another folder. When I run it locally in Alteryx Designer, it 
works just fine and I get the expected output. When I run it in 
Alteryx Gallery, the workflow completes with no errors but it 
doesn't give me the expected out. It goes through the tabcmd step 
and the first powershell script with the correct output, but does 
not perform the second powershell script correctly. Please see 
below for script, the --- are there to omit sensitive information.
