Cannot attach to .Net Functions (coreclr)

[rbdalvi]

Issue Description

This started to occur after VS Code automatically upgraded to 1.54.1 on restart. Downgrading to earlier version resolves this issue. But then VS Code auto-upgrades on restart and the problem returns.

Raised https://github.com/microsoft/vscode/issues/118343 with VS Code folks. But they determined it is caused by the C# extension. At least one other person @dochoss is facing the same issue.

NOTE: I have the following in a global.json file in the root folder to force SDK 3.1 instead of 5.0 { "sdk": { "version": "3.1.402" } }

Steps to Reproduce

Create a .Net Function (coreclr) written in C# and hit F5.

Expected Behavior

Debug toolbar should appear on the top of the editor.

Actual Behavior

Getting error "Cannot read property 'map' of undefined'".

Logs

OmniSharp log

Unavailable.

C# log

Unavailable.

C# debugger log

Followed https://github.com/OmniSharp/omnisharp-vscode/wiki/Enabling-C%23-debugger-logging#full-method But this did not print anything in the terminal.

You may need to follow up with a different extension (Azure Tools?) since it sounds like your failure is before getting to the debugger.
