尝试像这样处理异常：

import pymongo
from pymongo.errors import InvalidBSON

drivers = mongodb_global('drivers')
filter_col = {
    "created": 1,
    "updated": 1,
    "_id": 1,
    "name": 1,
    "birthday": 1,
    "id_expiry": 1,
    "license_expiry": 1
}

data = drivers.find({}, filter_col)
driver_lst = []

for item in data:
    try:
        print(item)
    except InvalidBSON as e:
        print(f"Invalid document: {e}")

太奇怪了上面的代码尝试简单地返回具有特定列的文档，因此即使没有对日期列进行有效性检查，也应该可以工作。我在下面的集合上尝试了相同的代码，它确实工作：

import pymongo      
client = pymongo.MongoClient("mongodb://xxx:xxxx@localhost:27017/?authMechanism=DEFAULT"
filter_col = {
    "address": 1,
    "date": 1,
    "_id": 1,
}

db = client["test"]  
collection = db["customers"]

data = collection.find({}, filter_col)

for item in data:
    print(item)

它返回以下内容：

python .\script.py
{'_id': ObjectId('652bef9a87af75d75bc425ca'), 'address': 'Apple st 652', 'date': None}
{'_id': ObjectId('652bef9a87af75d75bc425cb'), 'address': 'Mountain 21', 'date': datetime.datetime(2018, 4, 15, 16, 54, 40)}
{'_id': ObjectId('652bef9a87af75d75bc425cc'), 'address': 'Valley 345'}
