# Raising Exceptions/Errors

There are two bricks for exceptional control flow:

* [Raise a Business Error](https://www.pixiebrix.com/marketplace/a1267ea0-01d6-4fe5-8716-04a05d2ec32e/raise-business-error/): logged as an error in error telemetry
* [Cancel Current Action](https://www.pixiebrix.com/marketplace/50828a07-67da-4d91-ac01-d19eb3b7b4d6/cancel-current-action/): not reported as an error. For example, the user cancelled a form

When a Raise Business Error or Cancel Current Action brick is run, the mod will stop running and the bricks following the brick will not be run.

If an error is raised in a Control Flow brick, the Control Flow brick will also error. However, when using the Try-Except and Retry bricks, the `try`-branch and retry `body` will handle the exception, and the mod will continue running.

## 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.pixiebrix.com/developing-mods/developer-concepts/control-flow/control-flow-bricks/raising-exceptions-errors.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.
