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.

[adrwh]

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.

[adrwh]

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.

Tried with freashly created function. still same error.

[nturinski]

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?

[lavibhatnagar]

Hi nturinski,

Yes, if you hit run on script debugger is getting attached which was happening it before.

Main Issue is when you try to hit F5 or press green button, func host will start and soon will throw the error mentioned above.

Here is my powershell integrated console version

Can we please get the solution soon?

[nturinski]

Hi lavibhatnagar, hitting F5 does work for me and attaches to the PS trigger for me. The only other thing that I tried was having a main.cs file in the root of my directory. It can be an empty file.

Unfortunately, this doesn't seem like something that our extension can fix directly, but I will keep working with you to try to figure out a workaround/solution.

[lavibhatnagar]

Hi @nturinski

i tried with creating new main.cs file in root directory. but still i am getting same error.

Are you able to make a request to function? i can only run the code if i run the script. all other option seems not working for me,

[adrwh]

For me, I can run "func host start" manually and get function output, but i cannot use breakpoints. If i try to run F5, i get ugly error messages Result: ERROR: Unable to find type [HttpStatusCode], which sounds like it cannot load the underlying libraries.

Hello, the issue can be fixed by changing your default Powershell Integrated Console to version 7 in vscode settings.json: "terminal.integrated.profiles.windows": { ..... "Powershell 7":{ "path": "C:\Program Files\PowerShell\7\pwsh.exe", "icon": "terminal-powershell" } }, "terminal.integrated.defaultProfile.windows": "Powershell 7",

Have you installed PS7? https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows?view=powershell-7.2

Installing .Net Core 3.1, x86 worked for me: https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-3.1.29-windows-x86-installer

[gammelgaard52]

What fixed the problem for me, was to install this: https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-desktop-3.1.29-windows-x64-installer

It's important that it's the Desktop version - other versions did NOT solve the problem.

I also had to update "powershell.powerShellDefaultVersion" from "Windows PowerShell (x64)" to "Windows PowerShell"

[lavibhatnagar]

I have installed dot net runtime windows installer (x64) and also updated PS 7 veriosn to the latest, and it did fixed the issue.

same issue for me, and nothing here works. PowerShell 7.2 PowerShell v4 Function

Same error. The function host starts. grpc error comes up, VS Code debugger doesn't attach.

I was able to resolve this to update extensionBundle in host.josn to: { "version": "2.0", "extensionBundle": { "id": "Microsoft.Azure.Functions.ExtensionBundle", "version": "[3.3.0, 4.0.0)" } }

After restarting VSCode it worked again

Can anyone else confirm that updating the extension bundle resolves the issue for them?

[manuelpazprad]

Hey guys in my case I had the same issue with that OmniSharp extension, In my case I saw that I had an error behind it, and was due the azure-core-tools package wasn't updated so I did the update as first step.

The I tried to run my function again and the problem persisted but this time the error behind changed, it said that my dotnet SDK was the version 7 and the core tools needed the version 6. So, I did the installation of the .NET DSK v6.

Now I'm able to execute my function and use the full capabilities of the debugger.
