Thanks for reporting this. We can also reproduce this issue, so we'll start investigating.

Do you have any idea when this started occurring? Or has the debugger never worked for Powershell 7?

[lavibhatnagar]

@nturinski i have no idea since when this issue started occurring, i encountered this issue on 15 june.

I'm running Mac M1 Pro Monterey 12.4 (21F79), this issue has been happening since around 25th May. I have played around with dot net core runtimes and SDKs v3 and v6 without success.

I made some initial progress by changing FUNCTIONS_WORKER_RUNTIME_VERSION to 7.2 (from the default ~7), and this got the to where the local debugging seems to start and run the local functions, no errors in the console, however pops up the above image, and the local functions are not actually running/listening.

Hi

Is there any update on this?

[alexweininger]

Could you provide any output from the Powershell Extension Logs and the Omnisharp Log output channels?

Based on this comment, I got it working by adding an empty main.cs file to the root of my workspace.

I reinstalled the C# extension, and there seems to be improvement. I can now run a normal F5 debug without getting the Omnisharp popup, however it kinda feels like the debugger is not attached to anything, none of my breakpoints are being hit, but i am getting output from the functions.

Here is my launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "PowerShell Launch Current File",
      "type": "PowerShell",
      "request": "launch",
      "script": "${file}",
      "cwd": "${file}"
    },
    {
      "name": "Attach to PowerShell Functions",
      "type": "PowerShell",
      "request": "attach",
      "customPipeName": "AzureFunctionsPSWorker",
      "runspaceId": 1,
      "preLaunchTask": "func: host start --powershell --verbose"
    }
  ]
}

The OmniSharp Log is empty
The PowerShell Extension Logs all look normal, no [Warning] or [Error] lines.

I created a fresh Function from scratch from VS Code and ran F5, heres the output.

Tried same thing but i am still getting same error. reinstalled c# extension.

Hi all,

I was running into the OmniSharp.Extensions.JsonRpc.RpcErrorException as well. After installing PowerShell 7.2 however, it seems to be attaching correctly:

Note that func host start still threw an error, but I hit "debug anyway"

Could you run $PSversionTable in the terminal that VS Code is running and verify the version number?
