@LuanVSO I have the same issue. I'm not an expert of pwsh, but a little investigation allowed me to run the script successfully if I removed . (dot) from my functions. I think it somehow connected with that issue https://stackoverflow.com/a/17881960/8413677. I tried to fix it in AstVisitor but I couldn't.

For example this is my function that failed:

 function dotfilesEdit {
     Set-Location $env:DOTFILES && nvim .
 }

@IISResetMe hello 👋 Do you have any idea how to fix it even conceptually?

@bedware can you share the original profile script + the full error message you saw? Please include the version of PowerShell you're using :)

Thanks!

I see the problem, the AST Visitor hasn't been updated to handle the short-circuit operators introduced in the latest versions of PowerShell. I'll get it updated and ship a new version sometime next week :)

[bedware]

Thanks! I will be appreciated =)

[bedware]

I just want to mention that in my case it was enough to merge the commands by ; to get around this problem. And that worked, too. But I want to warn you that is not the same as using && which will apply the second command only if the first command was successful.

function dotfilesEdit {
    Set-Location $env:DOTFILES ; nvim .
}

[IISResetMe]

I'm aware they behave differently, it's a question of timing - the chaining operators didn't exist in PowerShell when the latest version of PSProfiler was released :)

[IISResetMe]

@bedware @LuanVSO New release should fix this bug, please give it a spin: https://www.powershellgallery.com/packages/PSProfiler/1.0.5.0 :)

[LuanVSO]

Working fine now, thanks
