Error Handling for N/http Module Functions in SuiteScript

The N/http module in SuiteScript facilitates making HTTP calls from server or client scripts. A key aspect of utilizing this module involves understanding error handling and the importance of parameter validation. Particularly, the method designed to count lines in a sublist is sensitive to missing required arguments, which can lead to errors if not addressed properly.
