# Show an error message in a workflow

Use workflow exceptions to show a customized error message in your Collibra Platform from a workflow.

To notify users that something went wrong with a workflow activity, incorporate the following code into your Groovy script task:

```groovy
// #importFile NONE
import com.collibra.dgc.workflow.api.exception.WorkflowException

WorkflowException collibraError = new WorkflowException("Exception description.")
collibraError.setTitleMessage("Exception title")
throw collibraError
```

You can download an [example workflow](https://cdn.collibra.com/developer/ExceptionExample.zip) to see how an exception works.
