### Raise Error Action Properties

In a message flow, use the raise error action to raise an exception with a specified error code (a string) and description.

In the Message Flow Editor, click a raise error action to display its properties in the Properties view. Use these properties pages to configure the selected raise error action. The pages are:

The Raise Error page has the following options:

Use the Comment page to add a comment, if desired:
