No, it is a new record in view trigger, and that field is in the filters for this view too. That means that field can’t be empty when the record shows in that particular view.
I’ve experienced this issue too, @Fernando_Martinewski.
I worked around it by creating a formula field that pulls in the value from the lookup field and concatenates it with an empty string, just to be sure it comes through as a string, like this:
{Lookup Field} & ''
Then I target that Formula field in my automation instead of the Lookup field. It seems to work much better.
It’s a little frustrating that we have to do this, and to have that extra field hanging around, but it’s easy enough to keep it hidden, so it’s mostly unobtrusive.
Not sure what the issue is, exactly, with the Lookup fields, but hopefully Airtable will see this and look into it.
