I have requirement where i have to query Users those permitted field not exsists.

My Approach to query data

const waitListQuery = query(usersColRef, where('permitted', '==', null)

but it's always return empty array []

Example DataSet:-

[  {..., permitted: true }, { ..., permitted: false }, { ... } ]

Any idea how to make query work?

Is this working ?:- where('permitted', '==', FieldValue.delete()) – Rajendra A Verma Jun 20 '23 at 16:53
@RajendraAVerma let me try – Zain_Ul_Din Jun 20 '23 at 16:54
`- deleteField() can only be used with update() and set()` – Zain_Ul_Din Jun 20 '23 at 16:58
Firestore doesn't have queries for fields that don't exist. Such a query would not scale in the way the Firestore requires. – Doug Stevenson Jun 20 '23 at 18:12
@DougStevenson Thanks! – Zain_Ul_Din Jun 20 '23 at 18:21
