+## Scenario: Cmdlet failing in PnP PowerShell runbook on Azure Automation
+
+### Issue
+
+When a runbook writes a PnP PowerShell-generated object to the Azure Automation output directly, cmdlet output can't stream back to Automation.
+
+### Cause
+
+This issue is most commonly caused when Azure Automation processes runbooks that invoke PnP PowerShell cmdlets, for example, **add-pnplistitem**, without catching the return objects.
+
+### Resolution
+
+Edit your scripts to assign any return values to variables so that the cmdlets do not attempt to write whole objects to the standard output. A script can redirect the output stream to a cmdlet as shown below.
+
+```azurecli
+  $null = add-pnplistitem
+```
+If your script parses cmdlet output, the script must store the output in a variable and manipulate the variable instead of simply streaming the output.
+
+```azurecli
+$SomeVariable = add-pnplistitem ....
+if ($SomeVariable.someproperty -eq ....
+```
