No array filter found for identifier 'element' in path-CodePudding

I am trying to update the notifications property from false to true by using MongoDb's arrayFilters. This is what the array/object looks like

This is what I have tried:

  '$set':
    {
     
      "userObject.$.notificationsArray.$[element].notifications"  : true
    },  

  }), { arrayFilters: [{"element": 'e8b7589f-cc72-4fb3-a38b-855ae1106ab2'}] }

but I keep getting this error: No array filter found for identifier 'element' in path 'userObject.$.notificationsArray.$[element].notifications'

What am I doing wrong?

CodePudding user response：

The entire document model isn't shown in the question, but perhaps this is enough to show how to use "arrayFilters" for the task.

db.collection.update({
  "_id": 0
},
{
  "$set": {
    "userObject.notificationsArray.$[current].notifications": true
  }
},
{
  "arrayFilters": [
    {
      "current.chatroom": "e8b7589f-cc72-4fb3-a38b-855ae1106ab2"
    }
  ]
})
