Unable to run POSH-SSH commands in some of my linux machines

[viju3010]

Hi Team, I am noticing the below issue when trying to list "Get-SSHTrustedHost". This happens one some of my jenkins slaves and I have multiple things including to reinstall the module.

[root@vcavst-wdc-slave1 ~]# pwsh
PowerShell 7.3.3

PS /root> Get-SSHTrustedHost
MethodInvocationException: Exception calling "GetAllKeys" with "0" argument(s): "Additional text encountered after finished reading JSON content: }. Path '', line 33, position 0."

PS /root> Get-Module Posh-SSH

ModuleType Version    PreRelease Name                                ExportedCommands

My Code :

# Remove trusted host keys to make host key validation succeeds
try{
    Write-host "Removing trusted host keys from the local host"
    $removeTrustedHosts = Get-SSHTrustedHost -Hostname $VC_ip | Remove-SSHTrustedHost -ErrorAction SilentlyContinue
#    Invoke-Expression "ssh-keygen -R $VC_ip"
    Write-host "Removed trusted host keys from the local host"
}
catch{
    Write-host "Could not remove trusted host keys"
    Write-Host $_.Exception|format-list -force
}

Error :

Removing trusted host keys from the local host

and what

Additional text encountered after finished reading JSON content

you see in $env:USERPROFILE\.poshssh\hosts.json ?

line 33, position 0.""

[viju3010]

{
  "Keys": {
    "xx.xx.0.14": {
      "HostKeyName": "xxxx",
      "Fingerprint": "xxxxxx"
    }
  }
}
}

Looks like an additional bracket at the end

After removing the } in the end, the commands are working. Thank you !
