Hello Aritra,
I am trying to do a similar but simpler thing.
The requirement is to read the file the file only and send it as part of the parameters to the web service URL.
I am unable to read the file though.
Although I could get the FileInfo for the file like file name etc. , but I am unable to read the file.
How did you manage to configure the temporary storage for the storage of file ?
Kindly share the detailed steps taken.
Thanks in advance

Regards,
