Vscode-powershell: Debug cannot read property 'onError' of undefined

Created on 23 Oct 2018 · 5Comments · Source: PowerShell/vscode-powershell

Issue Description

Insiders only (works fine in Stable): every time I try to start a debug session (either press F5, or use the Start Debug command), regardless of the debug type I select (Interactive Sessions, or Current File etc...) I always get the error in the screenshot.
I can reproduce with all extensions disabled (except Powershell of course), I tried to clean my C:\Users\carloc.vscode-insiders\extensions folder (basically reinstall the extensions from scratch) but the problem remains.

I use Code Insiders as my primary editor, I think I got this error the first time towards the end of last week but I don't have exact dates to confirm
