Wndows Task Scheduler Not Executing PS Script

Hi I have a script which reads files from a network path and uploads to sharepoint library and then moves to another archive folder.

It works fine if I run it manually

When I schedule it, in the task scheduler it says running and then after sometime ready state with (0x1) as code

When I schedule from task scheduler, I have a service account with admin privileges over the network path.

I have given these paramters

Start Program : Powershell

Add arguments : -executionpolicy bypass -Command & {"\\server1\data02\spscandocs\spupload.ps1"}

Start in : \\server1\data02\spscandocs

Any idea what I m doing wrong here
