How can I create custom error messages in my n8n workflow to provide more user-friendly feedback?

Within your `catch` block, you can use the `return` statement to return a custom error message. This message can be displayed to the user or logged for further investigation. Format the message to be informative but not overly technical. Consider using conditional logic to provide different error messages based on the specific error type. You can also return an error status code to indicate failure.
