This error typically appears when a new SuiteScript record is created in NetSuite. It happens because module APIs are being used directly inside define and not inside any functions.
For example:
To fix this, make sure all module functions and enums are placed strictly inside functions.
For example:
Note:
NetSuite performs this validation only when the script record is initially created. After the script record already exists, updating the code will no longer trigger this validation, so using certain enums or functions outside of a function block will not cause issues.
