Anyone know how to generate a GUID in SuiteScript? There is info on GUID for Secretkey in the Crypto module, but is not what I'm looing for

pick your favorite uuid package from npm

They are node modules which do not seem to work in Netsuite due to dependancies

some are node only, some support browsers

I found this one, which is a single script. Problem is the UUIDs generate are not unique https://github.com/rse/pure-uuid

choose v4 to get random uuids

They are random for a while, but eventually it generates duplicates

as in you saw it generate a duplicate?

Yes, several duplicates with 60k generated uuids

what did the script look like

Not exactly sure what you mean. I called this uuid script via a Sales Order User Event script to assign a uuid value for each Sales Order. I created a function to get the uuid which is ...

const getNewId = () => {
            const newUuid = new uuid(4);
            return newUuid.format();
        }

you will probably have to polyfill it yourself
