Are logging messages of level ERROR logged in a Mule app with the default configuration?

Explanation:
Logging levels determine what gets written to the logs. With the default Mule configuration, the runtime is set up to be less verbose and does not emit ERROR-level messages by default. If you want to see errors in the logs, you need to opt in by adjusting the logging settings—for example, changing the root logger level or adding a dedicated logger configured to ERROR in the log configuration (such as log4j2.xml) or enabling specific error-logging options. So, by default, ERROR messages aren’t logged.
