Check Your MongoDB Connection

[[See Video to Reveal this Text or Code Snippet]]

Replace 'mongodb://localhost:27017/your-database' with your actual connection string.

Ensure Collection Existence

If you are attempting to access a specific collection, make sure that the collection exists in the specified database. MongoDB won't implicitly create a collection until data is inserted, so you may need to insert a document or explicitly create the collection.

Check Database Permissions

Ensure that the user associated with your MongoDB connection has the necessary permissions to read and write to the specified database and collection. Incorrect permissions can lead to the "Cannot read property 'collection' of undefined" error.
