[06:24:52] <kkoomen> Hi. I created a user schema where I have an email and mobile field. The mobile field should be unique but still allow null values and should only compare uniqueness with strings. Here's my debug info: https://jinb.in/b6fa81
[23:16:50] <xjsx> with an await db.collection('test').update({_id}, {$set: {hello: true}}), if the collection does not exist this does not create it. Why?
