powershell - Error "copy-item : The operation completed successfully" but it worked? -

i trying run following step in powershell, proceeds error out. file getting copied, i'm tempted workaround force , erroraction silentlycontinue. why happening? happens regardless of force flag, , regardless of file existing in target location.

note locations unc paths. added parts maybe make difference(?).

$rootpath = "\\servera\sharea" $stagedir = "$rootpath\submit"  #sample file $flagfl:  #-rw-rw-r-- 1 mname data 588573 aug 31 14:51 file16083101.000.z  $newfiles = get-content $rootpath\$flagfl |  foreach {$_.split(" ")[8]}  foreach ($thisfile in $newfiles) { $thisfile_unc=($thisfile).replace('.z','') $reccnt = (get-content $rootpath\$thisfile_unc | measure-object -line).lines $orionfile = "$thisfile_unc.$reccnt"  get-content $rootpath\$thisfile_unc |% {$_.replace("`n", "`r`n")} | out-file -encoding ascii -filepath $rootpath\$orionfile -force  copy-item $rootpath\$orionfile $stagedir -force  } 

error message:
