New-WinGetSource fails to publish Azure Web App

Brief description of your issue

I noticed the Microsoft.WinGet.RestSource just being released yesterday, so I was eager to try it out. When running the New-WinGetSource, it throws an error:

Steps to reproduce

Run New-WinGetSource -Name wingetsource -Verbose -InformationAction continue -ResourceGroup winget -SubscriptionName "<subscriptionName>" -ShowConnectionInstructions

Expected behavior

Deploys the WinGet source successfully.

Actual behavior

It fails uploading the .zip file to the Azure Function. This is because the default timeout is 10000 milliseconds, meaning 100 seconds. When attempting to manually upload the .zip file and set the timeout to 300 seconds, it succeeds.

The following line is responsible:

$DeployResult = Publish-AzWebApp -ArchivePath $RestSourcePath -ResourceGroupName $ResourceGroup -Name $FunctionName -Force -ErrorVariable DeployError

There are perhaps to possible solutions:

• Either increase the timeout
• Use the -Async parameter

A small side note, instead of doing this:

            Write-Information -MessageData "Publishing function files to the Azure Function."
            $DeployResult = Publish-AzWebApp -ArchivePath $RestSourcePath -ResourceGroupName $ResourceGroup -Name $FunctionName -Force -ErrorVariable DeployError

            ## Verifies that no error occured when publishing the Function App
            if ($DeployError -or !$DeployResult) {
                $ErrReturnObject = @{
                    DeployError = $DeployError
                    DeployResult = $DeployResult
                }

                Write-Error "Failed to publishing the Function App. Error: $DeployError" -TargetObject $ErrReturnObject
                return $false
            }

            ## Restart the Function App
            Write-Verbose "Restarting Azure Function."
            if (!$(Restart-AzFunctionApp -Name $FunctionName -ResourceGroupName $ResourceGroup -Force -PassThru)) {
                Write-Error "Failed to restart Function App. Name: $FunctionName"
                return $false
            }

You might shorten it to:

            Write-Information -MessageData "Publishing function files to the Azure Function."
            $DeployResult = Publish-AzWebApp -ArchivePath $RestSourcePath -ResourceGroupName $ResourceGroup -Name $FunctionName -Force -ErrorVariable DeployError -Restart # <-- Use restart right away

            ## Verifies that no error occured when publishing the Function App
            if ($DeployError -or !$DeployResult) {
                $ErrReturnObject = @{
                    DeployError = $DeployError
                    DeployResult = $DeployResult
                }

                Write-Error "Failed to publishing the Function App. Error: $DeployError" -TargetObject $ErrReturnObject
                return $false
            }

Start at the Publish-AzWebApp invocation in the issue and reproduce the New-WinGetSource deployment with the shown parameters. Check the timeout and -Async alternatives, then verify that the Azure Function receives the archive and the deployment completes successfully.
