Export Remote Registry Key - Receiving ERROR: Invalid key name-CodePudding

I'm trying to export a registry key on a remote machine using the code:

Foreach ($server in $servers)
            {               
                $backupFolder = $global:backupFolder
                $serverName = $server
                $backupFile = $global:backupFolder   '\'   $scmRef   "_"   $server   "_"   $userId   ".reg"
                $registryEntry = "HKLM:\SOFTWARE\South River Technologies\Titan FTP Server\Servers\2\Users\"

                Write-Host "Reg" $backupFile $registryEntry

                Invoke-Command -ComputerName $server -ScriptBlock {   
                    Write-Host "Creating Backup Folder on"$Using:serverName
                    New-Item -Path $Using:backupFolder -type directory -Force
                    Write-Host "Folder creation complete on"$Using:serverName
                    reg export $Using:registryEntry $Using:backupFile
                    Write-Host "Registry exported successfully to" $Using:backupFile
                }
            }

I'm receiving the error message and not sure why

ERROR: Invalid key name. CategoryInfo : NotSpecified: (ERROR: Invalid key name.:String) [], RemoteException FullyQualifiedErrorId : NativeCommandError PSComputerName : FRUSVAFD01

Type "REG EXPORT /?" for usage.

The code above creates the relevant folder correctly but cannot find the key name despite it being there. I've run locally as reg export HKLM:\SOFTWARE\South River Technologies\Titan FTP Server\Servers\2\Users\ C:\Users<username>\desktop\registryentry.reg and it runs correctly.

Any idea why this doesn't work remotely? I'm at my wits end and have wasted most of the day googling.

Thanks in advance

Your code probably needs a cleanup, but i think the issue is the colon in the registry path. Try changing this:

 $registryEntry = "HKLM:\SOFTWARE\South River Technologies\Titan FTP Server\Servers\2\Users\"

to this

 $registryEntry = "HKLM\SOFTWARE\South River Technologies\Titan FTP Server\Servers\2\Users\"
