Save Attachments: Value cannot be null. (Parameter 'key')/ System.ArgumentNullException

I’am so sorry… still not getting…

I dont know which file is a Path_CSV… :cold_sweat:
or I have to assign diff. file in “Read CSV”…

As a test, can you fill in the full file path of the CSV file directly in the Read CSV activity?

sorry… still not working…

Please share screenshots of the step and error.

Hi,

I see the variable Path_CSV is getting assigned inside if condition of for loop. Can you please check if the condition is getting satisfied and Path value is assigned.

Also, you can try to add if condition to read CSV file when Path_CSV value is not null or empty.
