Custom Python Command to read a CSV file

I have created a custom python command but I'm facing this problem. I have a dynamic fileName.
The filename that I want to read changes everyday.
It works fine before I package the code using the splunk streaming command.

with open('C:\Users\Desktop\%s\%s\%s'%('assetfiles','DailySchedule',fileName)) as csv_file:
This will give me:
C:\Users\KGQJ3999\Desktop\assetfiles\assetfiles\DailySchedule\2019-12-20_NAME1.csv

However, after packaging it into the streaming command, it's giving me this.
C:\Users\KGQJ3999\Desktop\assetfiles\assetfiles\DailySchedule\ .csv

I have tried many ways to concatenate strings. Even forcing the filename to be str(fileName). Still, the fileName is dissappearing from the splunk side and I'm getting the IO error.

Anybody has any idea why??

Is fileName a field that exists in your search results immediately before you | to your custom command? If not, I would have expected the script to error out (missing a required arg?) but perhaps it's carrying on with null/empty value and that's why you're getting a csv with no name?
