error handling in flow designer in servicenow: a comprehensive guide

flow designer in servicenow is a powerful tool for automating business processes. however, like any automation platform, unexpected errors can occur during flow execution. properly handling these errors is crucial for ensuring the robustness and reliability of your flows. without adequate error handling, flows can fail silently, leading to data inconsistencies and business disruptions.

this tutorial will delve into various techniques for error handling in flow designer, providing code examples and best practices to help you build more resilient flows.

**1. understanding the basics of error handling in flow designer**

* **error states:** a flow can encounter errors at various points, including:
* **action failures:** when an action within the flow encounters an issue (e.g., invalid data, network connectivity problem, record not found).
* **script errors:** when server-side scripts used within the flow throw exceptions.
* **connection issues:** when a connection configured within the flow becomes unavailable.
* **concurrency conflicts:** when multiple flows try to update the same record simultaneously.

* **default behavior:** by default, when an error occurs in a flow designer flow, the flow stops immediately, and an error message is logged. this behavior is often insufficient for production environments, as it can leave tasks incomplete and interrupt workflows.

* **error handler flow logic:** the flow designer provides a dedicated "error handler" flow logic that allows you to define specific actions to be taken when an error occurs. this gives you control over the flow's behavior in the event of a problem.

**2. using the error handler flow logic**

the cornerstone of robust error handling in flow designer is the "error handler" flow logic. here's how it works:

1. **adding an error handler:**

* open your flow in flow designer.
* click on the "add ...
