Error Loading a workspace on the local machine

I was trying to load a workspace into a local folder using the scm command line -
c:\RTC_Workspace>scm load Work0 -r https://sdwaix9.in.ibm.com:9443/jazz/ -t C:\RTC_Workspace\Work0(folder where i want the files to be loaded)
where Work0 is the name of the workspace to be loaded

i am facing an error in this ->
