# 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. --- # Agent Instructions: 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.
