Invalid expression error, but expression works in different environment

I have a script that I created that automates a join and field calculation process across multiple feature classes. The script works when I test locally, but when I move it to another test environment, I receive an Invalid Expression error. Wondering if this could potentially be a permissions issue, or what could be causing this. The only differences between environments are the connection paths.


Here is the error message:


Traceback (most recent call last):
File "C:\Users\vueworks\Desktop\MDCETL\", line 64, in <module>
vwfcin = arcpy.MakeTableView_management(sde+"\\"+vwfc, vwt)
File "C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\", line 7047, in MakeTableView
raise e
ExecuteError: ERROR 000358: Invalid expression

And the script.
