How do you override application properties?
You can configure your Mule application to automatically load properties from properties files based on different environments (Production, development, testing, QA) using property placeholders.
1. Create a properties file for each development environment in your Mule application.
2. Configure a property placeholder in your application to look for the environment at the time of launch.
3. Set environment variable one each for the different environment.
The property placeholder will then take up an environment variable value and based on that use the properties file.

In Mule4 how you can generate custom errors.
By using the Raise Error component
In Mule 4, how errors are handled in a mule flow?
When an error is thrown in Mule flow while processing an event first step is it stops normal flow execution and it will not go to the next components. Then depending on the error type either error will be caught and handled inside the error handling block or thrown up to its parent flow.
Where we can add an error handler in the Mule 4 application?
An error handler can only be added to
– A flow
– A private flow
– A Try scope
– An global error handler (outside of any flows) is then referenced to any of the error handling strategies.
Note: Error handler can not be added to subflows.
What is the Mule default error handler?
When there is no error handler defined for any flow or by using try scope, the Mule default error handler will be used. This default handler should be configured globally.
What if the default error handler not configured in the Mule application?
If the default error handler is not configured then Mule runtime will provide its own default behavior
– First, it stops the execution of the flow and logs information about the error.
– Implicitly and globally handles all errors thrown in Mule applications.
– It automatically rethrows the error.
– Most important we cannot configure it.
What are error scopes in mule4 to handle errors?
– On Error Continue scope
– On Error Propagate scope
Can you please explain the difference between these two error scopes in Mule4?
What is the use of Try scope in Mule4?
Try Scope is very useful when you need to group a set of events/ components and want to handle errors based on your specific requirements. It acts as a private flow inside the parent flow. For Unhandled errors, it propagates to its parent flow.
