Action with error monitor allows you to create a series of actions that will be performed when a pre-determined action step encounters an error. When you create a new recipe, you will see four new actions being created as shown below:
The second step is the action that you would like to be monitored for errors, and the fourth step is what you would like to happen in the event of an error. In this example below, I set it in such a way that if my attempt to get details of a specific object in Salesforce fails and shows an error, it will send an email to me notifying me of the error and details of the error. The 2 actions are set up like a normal action is. You can check out this article if you're unsure of how to do that.
