KeyError when running lu_field with a store already containing data about emmet HOT 2 CLOSED

Hey Richard, the lu_filter works by finding the maximum date of the target store for all values corresponding to the lu_field (by default this is "last_updated") and only getting documents from the source store which have lu_fields which are greater than that, this ensures that only documents which have been added to the source store after the latest entry in the target store are used in the build. I suspect that the issue is that surfprops_store might not have a last_updated field?

If not, you can either add such a field to your documents with the current date, or you can select another field you want to use for this purpose .
