Hi @Gokul_Murali ,
To understand more about the error being faced inside the Invoke Code, try using Try Catch Block inside it.
We would require to handle the Exceptions inside Invoke Code Activity to be able to understand where/what was the exact error.
Also, let us know what does the Current_Date value contain. If you are using \ OR / in the Current_Date value, it would result in an error as a file name cannot contain these characters.
