Advanced NetSuite SuiteScript Debugging: Techniques Beyond the Standard Logs

Debugging SuiteScript in NetSuite can be frustrating, especially when dealing with silent failures, asynchronous script execution, or unexpected behaviors in server scripts. While the standard nlapiLogExecution or log.debug() functions work well for simple debugging, more advanced techniques are needed for complex issues.

Advanced Debugging Techniques

2. Using Script Execution Logs with Filters

• Navigate to Customization > Scripting > Script Deployments.
• Locate your script and check the execution logs.
• Apply filters based on execution context, user, or script name to isolate issues.

2. Real-Time Execution Monitoring via Execution Context

• Use runtime.executionContext to verify where the script is running (USER_INTERFACE, CSV_IMPORT, SCHEDULED, etc.).
• Example:

javascript

Copy

Edit
var context = runtime.executionContext;
log.debug({ title: 'Execution Context', details: context });

2. Handling Silent Errors with Try-Catch and Email Notifications

• Instead of letting errors disappear into logs, send an email when an error occurs:

javascript

Copy

Edit
try {
    // Code that might fail
} catch (e) {
    email.send({
        author: -5,
        recipients: 'admin@yourcompany.com',
        subject: 'SuiteScript Error Notification',
        body: 'Error Message: ' + e.message
    });
}

2. Logging Variable State in JSON Format for Deep Inspection

• Instead of logging individual variables, log complex objects as JSON for better readability:

javascript

Copy

Edit
log.debug({ title: 'Response Data', details: JSON.stringify(responseData) });

By implementing these advanced debugging strategies, you can quickly identify and fix issues that are otherwise difficult to catch in NetSuite.
