      Description

      The bug shows even after running the following simple code:

      from pymongo import MongoClient
      import gridfs
       
      client = MongoClient('mongodb://localhost:27017/')
      db = client.my_app
      file_system = gridfs.GridFS(db)
       
      _id = file_system.put(b"hello world")
      print(_id)
      print(str(_id))
      print(file_system.get(_id).read())
      print(file_system.get(str(_id)).read())
      

      The error I got is:

      5e84dcec7ca83a32a5e09aa8
      5e84dcec7ca83a32a5e09aa8
      b'hello world'
      Traceback (most recent call last):

       print(file_system.get(str(_id)).read())
