Steps to Reproduce

Import-Module dbatools
Show-Command # Results in error
# For completeness, how I proved it was dbatools:
Remove-Module dbatools
Show-Command # No longer results in error.

Please confirm that you are running the most recent version of dbatools

2.1.7

Other details or mentions

After getting the full error details, it occurred to me based on the error that it was likely a command that took in a pipeline object, and something about the object. So to determine the command(s) causing issues I ran: get-command -Module dbatools | % { $cmd = $_.name; try { show-command $cmd } catch { Write-Host $cmd } } and just held down the Escape key to close all the Show-Command windows that appeared. It eventually came back with Remove-DbaReplArticle and Remove-DbaReplPublication. Based on the error variables from those commands it looks like it's the Microsoft.SqlServer.Replication.Publication and Microsoft.SqlServer.Replication.Article types causing issues.
