az functionapp show consistently fails the first time

As per the title.

Specifically:
Running a yaml pipeline in Azure Devops

modified example below.

```yaml
- task: AzureCLI@2
displayName: 'Get function urls and keys'
inputs:
azureSubscription: 'xyz'
scriptType: 'pscore'
scriptLocation: 'inlineScript'
inlineScript: |
Write-Host "rgName: $(rgName)"
Write-Host "functionAppName: $(functionAppName)"
$statusUrl = az functionapp function show --resource-group $(rgName) --name $(functionAppName) --function-name 'status' --query 'invokeUrlTemplate'
Write-Host "##vso[task.setvariable variable=statusUrl]$($statusUrl.Trim('"'))"
```

Specifically any such code like the above always fails the first time after the referenced function is deployed. It seems to work reliably and successfully every other time after.

Do I need to write a sleep loop to address this? :(

**Actual Result**
```
ERROR: (NotFound) Error retrieving function.
Code: NotFound
Message: Error retrieving function.
You cannot call a method on a null-valued expression.

+ ~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], ParentContainsErrorRecordException

````

**Expected result:**
$statusUrl has a non-null value and the script executes as expected.
