Cannot process argument transformation on parameter 'ShellStream'. Cannot convert the "Renci.SshNet.ShellStream" value of type "Renci.SshNet.ShellStream" to type "Renci.SshNet.ShellStream".

While triggering Invoke-SSHStreamShellCommand, I am getting Cannot convert the “Renci.SshNet.ShellStream” value of type “Renci.SshNet.ShellStream” to type “Renci.SshNet.ShellStream”. Error on azure devops pipeline.

How to resolve this issue.

I had the same problem with Posh-SSH version 3.0.1. For me the solution was to manually delete Renci.SshNet folder from C:\Windows\Microsoft.NET\assembly\GAC_64

@bbrown2008, I think this PS command could helped in your case: [System.AppDomain]::CurrentDomain.GetAssemblies() | ? { $_.Location -like '*GAC*Renci.SshNet*' } It shows locations of all Renci.SshNet dlls from all GAC locations after you import Posh-SSH module.
