Microsoft.PowerShell.EditorServices.ScriptFile.ValidatePosition out of range

[codykonior]

Hi,

I'm using VS Code 1.17.2, VS Code PowerShell 1.5.0, which bundles 1.5.0 of this module. When I trigger debugging, my debug sessions often terminate unexpectedly along with my PowerShell terminals. This is on Windows Server 2012 R2.

Name                           Value

Here's the relevant part of the logs (there's some lead up but it's at the end):

    PowerShell Editor Services is terminating due to an unhandled exception, see previous logs for details.

That ValidatePosition part is causing everything to crash - I've got hundreds of crash dumps ending in it. I'm not sure which part of the 3 components is responsible but it seems to be this - hence the issue.

Hope that helps.

Thanks for reporting this.

Probably a bit late know but do you recall which file you were editing and what was on line 174?

    Parameter name: Position is outside of column range for line 174.

I think this will be fixed in the upcoming 1.5.1 release. If you encounter the same issue again, please re-open this issue.
