error establishing client to placement service

[Annonator]

Hi all,

i recently played around with Dapr and the vscode plugin, i installed the most recent runtime / CLI https:/dapr/dapr/releases/tag/v0.5.0
https:/dapr/dapr/releases/tag/v0.5.1

My sample application runs without any major problems if I manually user daprd, dapr and attach the debugger. However, after installing the extension I did "scaffold dapr tasks" and i do run in the following error when executing the task:

> Executing task: daprd-debug <

> Executing command: daprd --app-id "GamedevFabric" --app-port "3000" --placement-address "localhost:50005" <

As a note here, if I start daprd, dapr manually i only use the following:

daprd --app-id "GamedevFabric" --app-port "3000"
dapr run --port 3501 --app-id GamedevFabric --app-port 3000 dotnet run

and I can attach my debugger to it without any problems. The main difference here is that i do not define a placement service address which is done automatically when i use the extension.

This problem might be very well related to my setup, what I'm struggling with is the amount of control i have to fix this through the plugin as I could not find a way to not set a placement-address through configuration (which might be just missing knowledge)

My launch.json:

{
        "name": "Custom Run with Dapr",
        "type": "coreclr",
        "request": "launch",
        "preLaunchTask": "daprd-debug",
        "program": "${workspaceFolder}/GamedevFabric/PlayerService/PlayerActor/bin/Debug/netcoreapp3.1/PlayerActor.dll",

        "console": "internalConsole",
        "stopAtEntry": false,
        "postDebugTask": "daprd-down"
    }

and my tasks.json

{
            "appId": "GamedevFabric",
            "appPort": 3000,
            "label": "daprd-debug",
            "type": "daprd",
            "dependsOn": "build"
        },
        {
            "appId": "GamedevFabric",
            "label": "daprd-down",
            "type": "daprd-down"
        }

@Annonator Are you on Windows, by chance? Looking into this, I think I may have found an issue where the default placement address is supposed to be different on Windows vs. other platforms but, for whatever reason, the issue wasn't apparent in prior versions.

In any case, if you're on Windows, try setting the placementAddress property in your daprd-debug task to localhost:6050 and see if that resolves the issue.

[Annonator]

Yes I'm running on windows :)

Added the property and i can confirm that it works now.

[ElanHasson]

This gets really tricky when you are running windows, but using dev containers on WSL2, with native docker :)

I can confirm this also works in my configuration:

 {
            "appId": "core-tenant",
            "appPort": 5000,
            "label": "daprd-debug",
            "type": "daprd",
            "placementAddress": "dapr_placement_dapr-dev-container:50005"
        },

@ElanHasson Glad the workaround works. Yes, WSL2 might make things interesting. How are you running the Dapr extension, "locally" (i.e. in Windows) or "remotely" from WSL2?

[ElanHasson]

Remotely, from Dev containers via in WSL2
