Hi @Sachin Wandale ,
Based on the error "Could not find a part of the path 'C:\Users.......csv'", looks like the issue is, while executing the runbook its not able to find the input CSV file in the expected path.
Are you executing the runbook in a Hybrid worker or in Azure sandbox itself?
Can you share your script or runbook?
If its on Azure sandbox, its better to copy the CSV file to $ENV:temp location and then use it.
