I would like from my collection to read only documents where a specific field doesn't exist, I tried with isNull: true but it doesn't work.

Firestore queries are based on data in its indexes. It can only return documents that *do* exist in the indexes, so it can't return documents for which a field doesn't exist. – Frank van Puffelen Apr 17 '23 at 23:34
