Unable to use $near

[martinsJoseph]

Hello guys,
I am having issues with using flask-mongoalchemy to query my database and get results that are close to the longitude and latitude I passed.

My Model:

class Event(db.Document):
meta = {
'indexes': [
("*location.coordinates", "2dsphere")
]
}

user_id = db.StringField()
uuid = db.StringField()
name = db.StringField()
address = db.StringField()
start_time = db.DateTimeField(required=True, default=datetime.datetime.now())
end_time = db.DateTimeField(required=True, default=datetime.datetime.now())
location = db.DictField(db.AnythingField())

When an event is created this is how the document is meant to look like:
{
"address": "Surulere",
"end_time": "2019-10-13T00:00:00",
"location": {
"coordinates": [
-119.3996898,
19.6255545
],
"type": "Point"
},
"name": "Amazonss__",
"start_time": "2019-10-12T00:00:00",
"user_id": "3b15b5f9d6d1ab93d14db52cabe6ac",
"uuid": "baa75b69047369a48342e6939c56d3"
}

And My Code for Querying is:
event = Event.query.filter({"location" :
{ "$near" :
{
"$geometry" : {
"type" : "Point",
"coordinates" : [longitude, latitude] },
"$maxDistance" : 4000
}
}
}).first()
