Database name mismatch between import folder and notebook

As “readme” shows, the folder to do mongorestore is “/m220py/data”, which have the subfolder (thus become database name) “mflix”. However, in the notebook “your_first_read”, the settings are:
client = pymongo.MongoClient(uri)
m220 = client.m220
movies = m220.movies
And it need the database name to be “m220”.
On the other hand, in notebook “MongoClient” it is “mflix”.

So I guess the m220 in “your_first_read” notebook should be changed to mflix?

That seems to be an issue.
Meanwhile, please use your cluster connection string and mflix as a database.
