Error while executing geo spatial query in MongoDB using Python

Question

I have just started working with Geo Spatial data using MongoDB and Python. Below is my code. For normal queries it works fine but for 'near' query I am getting error.

 from pymongo import MongoClient

client = MongoClient("mongodb+srv://dummyuser:dummypassword@cluster0.xprs.mongodb.net/test?retryWrites=true&w=majority")
db = client["MyDB"]
col = db["MyCollection"]
query = """{
geometry: {
$near: {
$geometry: {
type: 'Point',
coordinates: [77.25467696734609,28.63449787747656]
},
   $maxDistance: 5000,
   $minDistance: 10
  }
 }
}"""

docs = (col.find(query))

for doc in docs:
  print(doc)

While executing this code I am getting below error

C:\user\Python\parse-payment-response\venv\Scripts\python.exe C:/user/Python/jsonParser/mongoclnt.py
Traceback (most recent call last):
  File "C:/user/Python/jsonParser/mongoclnt.py", line 24, in <module>
    docs = [(col.find(query))]

    raise TypeError("%s must be an instance of dict, bson.son.SON, or "
TypeError: filter must be an instance of dict, bson.son.SON, or any other type that inherits from collections.Mapping

Please help

After lots of effort and search I got this fixed. Code as below:

from pymongo import MongoClient

MongoClient("mongodb+srv://dummyuser:dummypassword@cluster0.xprs.mongodb.net/test?retryWrites=true&w=majority")
db = client["MyDB"]
col = db["MyCollection"]
query={"geometry": {"$nearSphere": {"$geometry": {"type": "Point", "coordinates": [77.25467696734609, 28.63449787747656]}, "$maxDistance": 2000,"$minDistance": 10}}}
docs = col.find(query)
for doc in docs:
  print(doc)
