Creates null value item in firebase on init fetch on table(because runs update item)

I have a table with items from firestore. At the same time I have query to update item, which runs automatically when inputs change. So this query runs when I open table and creates new item on Firestore with null values. Is that ok?

Hi @Nurbek! Whether it's ok for our Firestore db to have those null values is ultimately up to you.

But we'd generally recommend switching your update query to "Run only when manually triggered", and then hook the update up to some kind of button or other component in your app.
