Understanding and Managing HTTPS Request Errors in NetSuite Scripts

Handling errors in HTTPS requests is a critical aspect of scripting in NetSuite. Developers leveraging the N/https module must be aware of various potential errors and timeouts that could impact the functionality and reliability of their scripts.

Common HTTPS Request Errors

NetSuite's N/https module supports both client and server-side scripts, allowing developers to send HTTPS requests efficiently. However, handling errors is crucial to maintain stable integrations.

SSS_INVALID_HOST_CERT

This error occurs when there is a problem with the certificate used by the host. It's often triggered if the server's certificate is untrusted or improperly configured. Tip: Always verify that the server's certificate is valid, trusted, and that the domain name in the options.url parameter is correct and adheres to DNS rules (i.e., no more than 63 characters, alphanumeric with hyphens, and starting/ending with a letter or digit).

SSS_INVALID_URL

Ensure that the options.url provided is a fully qualified URL. Mistakes in URL configuration or missing components (like scheme or domain) trigger this error. Always validate URLs before including them in scripts.

SSS_MISSING_REQD_ARGUMENT

Triggered when mandatory parameters like options.method or options.url are not specified. Best Practice: Validate all inputs before making requests and ensure all required parameters are given appropriate values.

SSS_REQUEST_LOOP_DETECTED

This error is indicative of recursion beyond acceptable limits, typically due to a script calling itself repeatedly. Avoid infinite recursion by implementing checks in your script to prevent such loops.

SSS_REQUEST_TIME_EXCEEDED

Connection and request timeouts manifest as this error. If the server connection exceeds 5 seconds or the payload transfer extends over 45 seconds, this error will occur. Recommendation: Optimize request payloads and consider server performance and network latency when designing scripts.

Error Handling Strategies

Validation: Proactively validate input parameters and URLs before making requests.
Certificate Management: Keep track of certification validity and trust levels.
Timeouts and Retries: Implement retry logic and optimize request payloads for performance.
Error Logging: Log errors systematically to aid in troubleshooting and understanding patterns in failures.

Governance and Script Types

The N/https module adheres to a governance limit of 10 units per request. This module is available since NetSuite version 2015.2 and supports both server and client scripts.

Key Takeaways

Understand and manage common HTTPS errors like certificate issues, invalid URLs, and timeouts.
Always validate inputs to minimize the risk of errors.
Use optimal timing and logging strategies to deal with request and connection timeouts.
Familiarize yourself with governance limits and ensure scripts are within the unit consumption limits.

Proper understanding and management of these errors will significantly enhance the reliability of your NetSuite integration efforts.
