Why query operator $exists in console not show count?

in compass work
{atmosphericPressureChange: {$exists: false} }

in console NOT work
db.data.find({atmosphericPressureChange: {$exists: false} }).count()

Hi @Dima_36975,

Your query is correct and it should work on terminal. Please check the attached screenshot:

Please check that you are connected to the correct Atlas cluster, database and collection. If it still does not work for you, share the screenshot of the query.

Let me know, if you have any questions.
