Pymongo@MongoDB Atlas TypeError: 'Collection' object is not callable

Question

I am trying to use Pymongo to store data to MongoDB Atlas.

When deploying from a Windows 10 environment to Ubuntu Server, I get the following error.

It worked fine on Windows, so why is this happening?

from itemadapter import ItemAdapter
# import collections
import pymongo

class MongoPipeline:

    collection_name = 'all'

    def open_spider(self, spider):
        self.client = pymongo.MongoClient('mongodb+srv://xxxx:[email protected]/myFirstDatabase?retryWrites=true&w=majority')
        self.db = self.client['ShopDB']

    def close_spider(self, spider):
        self.client.close()

    def process_item(self, item, spider):
        self.db[self.collection_name].insert(dict(item)) # insert(dict(item))
