Why is my re-deployed Azure Function App not recognizing items put on a queue?

Lindsay Shelton 46 MVP

So I was getting an error after a long day of fighting with PowerShell, and in frustration, I just decided to delete a working Function App (in dev, I wasn't that on edge) and re-deploy it. This is the error I was getting - https://learn.microsoft.com/en-us/answers/questions/1462401/azure-functions-deployment-error-number-of-entries?page=2&orderby=helpful&comment=answer-1391572#answers. Ever since, I haven't been able to get the re-deployed Function App to recognize items put on the Azure queue (it's a queue trigger). I've checked the configuration settings for AzureWebJobsStorage five thousand times and I'm also unable to figure out how to get any error messages to help guide me in what's going wrong. I'm a junior dev who didn't build this - just had instructions in how to deploy it and make tweaks to the template.

Lindsay Shelton Thanks for posting your question in Microsoft Q&A. Were you able to upgrade Azure Resources extension to 0.8.3 version? From the description, you were able to redeploy function app, but queue is not triggering as expected. Correct?

Can you share Code snippet, function.json (removing sensitive info), function app name if possible?

No, I had to specifically down-grade Azure Resources extension to 0.8.0 to get it to deploy at all.

Function App Name is sci-provisioning-dev2.

Snipped from run.ps1:

# Input bindings are passed in via param block.
param([string] $QueueItem, $TriggerMetadata)

# Import the PnP.PowerShell module
Import-Module "$($TriggerMetadata.FunctionDirectory)\\PnP.PowerShell"

$cert = "$($TriggerMetadata.FunctionDirectory)\\cert.pfx"
$cert_password = (ConvertTo-SecureString -String $env:APP_CLIENT_PASSWORD -AsPlainText -Force)
$template = ""

if (Test-Path $cert) {
    # Proceed with using the certificate
} else {
    Write-Host "Certificate file not found: $cert" -ForegroundColor "Red"
    # Handle the missing certificate file scenario
}

Write-Host "Connecting with ClientId:$($env:APP_CLIENT_ID) to Tenant:$($env:APP_TENANT_ID)"
Write-Host "Processing Site - $($QueueItem)"
Connect-PnPOnline -Url $QueueItem -ClientId $env:APP_CLIENT_ID -CertificatePath $cert -CertificatePassword $cert_password -Tenant $env:APP_TENANT_ID

Function.json:

{
  "bindings": [
    {
      "name": "QueueItem",
      "type": "queueTrigger",
      "direction": "in",
      "queueName": "sites-queue-items2",
      "connection": "AzureWebJobsStorage"
    }
  ]
}

Oh nice, it just deleted my comment it seems, just what I'm in the mood for. I had to down-grade Azure Resources to 0.8.0 to get it to deploy at all.

Function App name is sci-provisioning-dev2

Opening of run.ps1

# Input bindings are passed in via param block.
param([string] $QueueItem, $TriggerMetadata)

# Import the PnP.PowerShell module
Import-Module "$($TriggerMetadata.FunctionDirectory)\\PnP.PowerShell"

$cert = "$($TriggerMetadata.FunctionDirectory)\\cert.pfx"
$cert_password = (ConvertTo-SecureString -String $env:APP_CLIENT_PASSWORD -AsPlainText -Force)
$template = ""

if (Test-Path $cert) {
    # Proceed with using the certificate
} else {
    Write-Host "Certificate file not found: $cert" -ForegroundColor "Red"
    # Handle the missing certificate file scenario
}

Write-Host "Connecting with ClientId:$($env:APP_CLIENT_ID) to Tenant:$($env:APP_TENANT_ID)"
Write-Host "Processing Site - $($QueueItem)"
Connect-PnPOnline -Url $QueueItem -ClientId $env:APP_CLIENT_ID -CertificatePath $cert -CertificatePassword $cert_password -Tenant $env:APP_TENANT_ID

Function.json

{
  "bindings": [
    {
      "name": "QueueItem",
      "type": "queueTrigger",
      "direction": "in",
      "queueName": "sites-queue-items2",
      "connection": "AzureWebJobsStorage"
    }
  ]
}

Ok, I just saw that they fixed Azure Resources so I re-upgraded to 0.8.3, re-deployed, and nothing. I'm occasionally getting this in the logs but I don't know where else to even chase this down at, I've tried everything Google and ChatGPT suggested: "2023-12-15T15:28:33Z [Verbose] Token audience validation failed for audience 'https://appservice.core.azurewebsites.net'."

Lindsay Shelton This would require investigation of backend logs to find the cause. Our support team has the best tools and resources to help with that. Do you have a support plan with us? If not, send an email to azcommunity@microsoft.com referencing this thread with your subscription ID (not name), function app details along with subject as "Attn: Muthu". I can assist you offline in enabling a one-time free technical support ticket.

I appreciate it - this is our dev environment so I doubt we have a subscription for that, but I'd imagine we do for prod. I'll email you, thank you.

Lindsay Shelton Thanks for your engagement and glad to see that your issue is now resolved.

Update for the community:

There was an issue with host.json configuration and it was resolved after removing the following lines of code:

"functions": [ "run.ps1" ]

Please checkout host.json reference for Azure Functions for more info about configuration options.
