Install powershell modules for Azure Functions not working

I'm trying to use dependency feature (https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference-powershell#dependency-management) but i can't get them working. I added few module (O365, ITGlue modules etc.). I tried to restart function app after changing requirements.psd1 but still nothing. I don't see any error in logs regarding dependencies. What I'm missing here?

See requirements.psd1 file

The first check would be to ensure that managedDependency property is set to true in your function's host.json file:

{
  "managedDependency": {
          "enabled": true
       }
}

Restart the app after updating the requirements.psd1 file with the modules you need. You can notice the updates being processed in the logs:

If you want to verify the installation, you can go to the Kudu site for your app, and navigate to the path D:\home\data\ManagedDependencies\<id>\ and find them listed:

Kudu

Another simple way of verifying the same would be to tweak the function to list it. For example:

using namespace System.Net

# Input bindings are passed in via param block.
param($Request, $TriggerMetadata)

# Write to the Azure Functions log stream.
Write-Host "PowerShell HTTP trigger function processed a request."

# Interact with query parameters or the body of the request.
$name = $Request.Query.Name
if (-not $name) {
    $name = $Request.Body.Name
}

$body = "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."

if ($name) {
    $body = "Hello, $name. This HTTP triggered function executed successfully."
}

# Associate values to output bindings by calling 'Push-OutputBinding'.
Push-OutputBinding -Name Response -Value ([HttpResponseContext]@{
    StatusCode = [HttpStatusCode]::OK
    # Body = $body
    Body = $(Get-Module -ListAvailable | Select-Object Name, Path)
})

Calling your function should now list all the installed dependencies: Example

Do note that Managed dependencies currently don't support modules that require the user to accept a license, either by accepting the license interactively, or by providing -AcceptLicense switch when invoking Install-Module. Also make sure that the runtime can access the PowerShell Gallery URL by adjusting any required firewall rules.
