It gives me 'Unexpected Suitescript Error'

is this a lot/serial number item? does it use bin?

Yes and yes.

my guess is the invalid expiration date, remove the line and try again

verify the IDs are correct and like Battk said the date format could be incorrect as you have Date and time both, normally it's just date.

Got it. Inventory adjustments have the field "adjlocation" not "location".
