Push-OutputBinding not working in ActivityTrigger

Using the standard VSCode function creation templates, I created an orchestrator with an activity function defined as:

function.json

{
    "bindings": [{
            "name": "name",
            "type": "activityTrigger",
            "direction": "in"
        },
        {
            "type": "queue",
            "direction": "out",
            "name": "outputQueueItem",
            "queueName": "outqueue",
            "connection": "AzureWebJobsStorage"
        }
    ]
}

run.ps1

param($name)

Write-Information "Pushing to outputQueueItem output binding"
Push-OutputBinding -Name outputQueueItem -Value "Queue item from Hello1"
Write-Information "Done"

"Hello $name!"

The Write-Information lines get logged, but no queue item is created. The same Push-OutputBinding works fine from other triggers such as an httpTrigger.

Repro attached.

• Queue item gets generated correctly when running http://localhost:7071/api/HttpTrigger1
• Queue item is not generated when running http://localhost:7071/api/orchestrators/DurableFunctionsOrchestrator1

@thunderstorm654 this is something I learnt from MS as it’s not intuative at all.

Open your function app in the Azure portal and select the Overview tab.

After a slight delay (maybe 10 seconds) in the Essentials section (at the top) you should see a See more link under tags (not the one next to properties. Click that and then Runtime version should appear under properties on the right hand side.

Brilliant thanks so much for replying - been wondering how to check this for a long time! Turns out it was hiding in almost plain sight all along 😃
