SuiteScript Debugger
Important:
SuiteScript 2.1 is now the standard scripting version. Update scripts that use SuiteScript 1.0 or the SuiteScript 2.0 or 2.x version annotations to SuiteScript 2.1 by the 2028.2 release to ensure continued compatibility. For more information, see Transitioning To SuiteScript 2.1.
NetSuite offers built-in tools so you can debug your SuiteScript 1.0, 2.0, and 2.1 scripts.
In SuiteScript Debugger help topics, the debugger for SuiteScript 1.0 and 2.0 scripts is called the Script Debugger, whereas the debugger for SuiteScript 2.1 scripts is called the 2.1 Script Debugger. To use either debugger, you must be using a role with SuiteScript permission (Full level).
