# Exception Handling

In complex use cases, typically with a lot of integrations or important services running on a schedule, errors are bound to happen at some point.

The action node Catch Exception may be used for catching exceptions and handling them. In some cases, you may even want to re-throw your own custom exception using Throw Exception action node (and catch them somewhere else).

In this Topic, we refer to the documentation of the Catch Exception action node. We also refer to an article (and Showroom example) of an Event Log design - where an Event logging and monitoring system is created.

**Articles**:

* [Catch Exception](/library/action-nodes/catch-exception.md)
* [Event Log Design](/how-to/logic-and-flow/event-log-design.md)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.appfarm.io/appcademy/appfarm-professional/logic-and-flow/exception-handling.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
