I need help, Not sure what im doing wrong. I keep getting this error:

True  

--------------------------------------------------------------------------- TypeError Traceback (most recent call last)  in  26 locateRec.locate(critter) 27 ---> 28 updateRec.update(changeCritter) 29 30 locateRec.locate(critter) /usr/local/datasets/animalsCRUD.py in update(self, record) 48 if record is not None: 49 ---> 50 update_result = self.database.animals.find_one_and_update(record) 51 return update_result.modified_count 52 else: TypeError: find_one_and_update() missing 1 required positional argument: 'update'

Here is my test code:

import pymongo from pymongo import ReturnDocument import datetime from animalsCRUD import AnimalShelter

#username = "aacuser" #password = "password"

insertRec = AnimalShelter("aacuser", "password") locateRec = AnimalShelter("aacuser", "password") updateRec = AnimalShelter("aacuser", "password") deleteRec = AnimalShelter("aacuser", "password")

animal = ({"age_upon_outcome":"5 years", "animal_id":"A333333", "animal_type":"Dog", "breed":"Derp", "color":"White", "date_of_birth":"07/19/19", "datetime": datetime.datetime.now(), "name":"", "outcome_subtype":"Foster", "outcome_type":"Adoption", "sex_upon_outcome":"Intact Female", "location_lat":30.60784677, "location_long":-97.35087807, "age_upon_outcome_in_weeks":64.24642857})

critter = {"animal_id":"A333333"}

changeCritter = ({"animal_id": "A333333"}, {'$set': {'animal_type': 'Cat'}})

print(insertRec.create(animal))

locateRec.locate(critter)

updateRec.update(changeCritter)

locateRec.locate(critter)

deleteRec.delete(critter)

And here is my python code:
