How to upload the file to Synology NAS with Tasker?

Question

I am trying to upload the file to my Synology NAS (DSM 4.5). Here is the API description. I am able to upload the file with Postman. But when I do it with Tasker, I am getting Invalid parameter error.

Here is the tasker code -

HTTP Request [ 
 Method: POST 
 URL: http://192.168.1.5:5000/webapi/DownloadStation/task.cgi 
 Body: api=SYNO.DownloadStation.Task&version=3&method=create
 File To Send: file:%TorrentFile1 
 Timeout (Seconds): 30 
 Use Cookies: On 
 Structure Output (JSON, etc): On 
 Continue Task After Error:On ]

Here is the console log of Postman:

and here is the captured request from the Tasker:

I see no difference.

What should I check or try?
