what is the format of the [params] ?

[omegawea]

i tried the following code:
method = 'create'
params = {
'params':{
"url": "http://torrent.com/abc.torrent",
"destination": "video/TEMPERORY",
}}
nas.downloadstation.task.request(method, **params)

File "...\Anaconda3\lib\site-packages\synolopy\devices.py", line 20, in validate
raise SynologyException(API_ERROR[code])

SynologyException: Invalid parameter

you mention that, in general, the command is:
nas.application.service.request(method, [params])

I wonder if you can tell me how to construct the input parameter [params]
