TypeError: ObjectId('') is not JSON serializable

Full error message
My response back from MongoDB after querying an aggregated function on document using Python, It returns valid response and i can print it but can not return it.

Error: 

TypeError: ObjectId('51948e86c25f4b1d1c0d303c') is not JSON serializable

Print:

{'result': [{'_id': ObjectId('51948e86c25f4b1d1c0d303c'), 'api_calls_with_key': 4, 'api_calls_per_day': 0.375, 'api_calls_total': 6, 'api_calls_without_key': 2}], 'ok': 1.0}

But When i try to return:

TypeError: ObjectId('51948e86c25f4b1d1c0d303c') is not JSON serializable

It is RESTfull call:

@appv1.route('/v1/analytics')
def get_api_analytics():
    # get handle to collections in MongoDB
    statistics = sldb.statistics

    objectid = ObjectId("51948e86c25f4b1d1c0d303c")

    analytics = statistics.aggregate([
    {'$match': {'owner': objectid}},
    {'$project': {'owner': "$owner",
    'api_calls_with_key': {'$cond': [{'$eq': ["$apikey", None]}, 0, 1]},
    'api_calls_without_key': {'$cond': [{'$ne': ["$apikey", None]}, 0, 1]}
    }},
    {'$group': {'_id': "$owner",
    'api_calls_with_key': {'$sum': "$api_calls_with_key"},
    'api_calls_without_key': {'$sum': "$api_calls_without_key"}
    }},
    {'$project': {'api_calls_with_key': "$api_calls_with_key",
    'api_calls_without_key': "$api_calls_without_key",
    'api_calls_total': {'$add': ["$api_calls_with_key", "$api_calls_without_key"]},
    'api_calls_per_day': {'$divide': [{'$add': ["$api_calls_with_key", "$api_calls_without_key"]}, {'$dayOfMonth': datetime.now()}]},
    }}
    ])

    print(analytics)

    return analytics

db is well connected and collection is there too and I got back valid expected result but when i try to return it gives me Json error. Any idea how to convert the response back into JSON. Thanks

You should define you own JSONEncoder and using it: import json from bson import ObjectId class JSONEncoder(json.JSONEncoder): def default(self, o): if isinstance(o, ObjectId): return str(o) return json.JSONEncoder.default(self, o) JSONEncoder().encode(analytics) It's also possible to use it in the following way. json.encode(analytics, cls=JSONEncoder)
