I'm trying to move over the extensions to the 2024.1 but now I get a internal error on a servicecontroller just retrieving a random custom list using nlapiSearchRecord

var sdOrigin = nlapiSearchRecord(
         "customlist_sd_origin",
         null,
         [new nlobjSearchFilter("isinactive", null, "is", "F")],
         [new nlobjSearchColumn("name")]
       );

Basically nothing special, and yes the custom list does exist and the search itself is functioning fine within NetSuite. What could be wrong? The moment I comment this search, my internal error disappears and the page is loading like it should

Is the Customer Center role your suitecommerce users have on their Access, set to have the needed List permissions?

I see the old version had elevated permissions enabled. Re-enabling those on the new servicecontroller fixed this issue

Unfortunately, one of the limitations of service files in extensions is that you need to elevate permissions each time you deploy.
