Powershell: No such file or directory when download via SCP on switch Aruba 2530

good morning, everyone,

I'm building a script to upload or download aruba 2530 switch configurations with powershell.

here are the operations I performed:

I've hidden a few things, such as the switch's IP address and my user folder.

After filling in the following: $credential = Get-Credential
I manually enter the SSH login user and password

via WinSCP I can access the contents of the switch but via Posh-SSH I can't.
Do you have any leads to give me, I'm drying ^^
Thank you for all !

PS C:\Users\xxx> Import-Module Posh-SSH

PS C:\Users\xxx> $credential = Get-Credential

PS C:\Users\xxx> Get-SCPFile -ComputerName "IP_Switch" -Credential $credential -RemoteFile "/cfg/running-config" -LocalFile "C:\Scripts\SwitchConfig.cfg" -AcceptKey -verbose

Start with the reported Get-SCPFile command and compare the Aruba 2530 remote path and SCP behavior with the successful WinSCP session. No repository file or test is named; done would mean reproducing the failure and identifying whether the path or Posh-SSH handling needs correction.
