Comprehensive and Detailed Step-by-Step Explanation:
* Understanding Scoped Applications:Scoped applications in ServiceNow are designed to isolate and protect application-specific code and data. Server-side scripts within scoped applications can use the gs (GlideSystem) object for logging and debugging purposes. However, not all gs methods are appropriate or valid for scoped applications.
* Valid Logging Methods in Scoped Applications:
* gs.info():This method logs informational messages to the system log. It is commonly used for general-purpose logging when developers need to track execution flow or display debug data.
Example:
gs.info('This is an informational log message.');
* gs.error():This method logs error messages to the system log. It is used to indicate problems or issues encountered during script execution. Example:
gs.error('An error occurred during script execution.');
* Incorrect Options Explained:
* gs.debug() (Option B): This method is not valid in scoped applications. It is a legacy logging method available in the global scope but restricted in scoped applications.
* gs.iog() (Option C): This is a typographical error and not a valid gs method in ServiceNow.
* gs.logError() (Option E): This is not a recognized ServiceNow API method. To log errors, gs.
error() is used instead.
* Best Practices for Logging:
* Logging should be meaningful and avoid unnecessary entries to keep logs clean and manageable.
* Avoid excessive use of logging in production environments, as it can clutter the system logs and potentially degrade performance.
