As it is noted in the change list of PoSh V5 here and you tagged your question with V4 the simple answer is probably your version's Copy-Item cmdlet does not provide that parameter
Copy-Item now lets you copy files or folders from one Windows PowerShell session to another, meaning that you can copy files to sessions that are connected to remote computers, (including computers that are running Nano Server, and thus have no other interface). To copy files, specify PSSession IDs as the value of the new -FromSession and -ToSession parameters, and add –Path and –Destination to specify origin path and destination, respectively. For example, Copy-Item -Path c:\myFile.txt -ToSession $s -Destination d:\destinationFolder.
I just ran into this today, but the root cause was the source folder I was copying from was empty. Once I put something in it to copy the -ToSession error went away.
