Errors are possible in any system and we can’t simply avoid errors rather we can implement our solutions with errors addressed and mitigated using various error handling techniques. Mule 4 provides a rich set of options to deal with any error scenarios in your implementations. Mule 4 provides On Error Propagate, On Error Continue options to deal with the errors that can happen at any processor level in your Mule Flow. Mule 4 also provides ways to deal with such errors at Global Level or at individual processor level using Global Error Handler or Try Scope respectively.
In this article and its associated video tutorial, you will learn how to handle errors in Mule 4 and how to use On Error Propagate, on Error Continue, Global Error Handler and Try scope in Mule 4 for handling Message Level Errors.
Mule 4 Error Handling Tutorial: How to Handle Errors in MuleSoft Mule 4
In the following video tutorial on YouTube Channel of TutorialsPedia, I have explained theoretical concepts of Mule 4 Error Handling and also demonstrated various use cases and examples about using Error Handler in Mule 4 Message Flows.
By the End of this Mule 4 Error Handling video tutorial, you will know how to:
- Use Error Handler at Main Flow and Child Flow Level.
- Use On Error Continue to handle errors and return success response.
- Use On Error Propagate to propagate errors from child flow to main flow and towards end-user.
- Configure Global Error Handler and handle errors at Global Level for Mule Flows.
- Use Try Scope to handle errors at individual processor level in any Mule Flow.
- Define Custom Error Types with custom error namespace and identifier.
- Modify error response for HTTP Listener to return JSON error response with custom response elements.
