  2. Use the neo4j object to create a new instance of the Driver with the credentials provided:

    • NEO4J_URI is the connection string

    • NEO4J_USERNAME and NEO4J_PASSWORD should be used to create the authentication token.

  3. Once you have created the Driver, open a new session and run the following query:

    cypher
    Find the Director

Your Answer

Who directed Toy Story?

Take the Director value output from the statement above and paste it into the box below.

  • ✓ John Lasseter

Hint

You need to call the neo4j.driver() object to create a Driver instance using the NEO4J_URI, NEO4J_USERNAME and NEO4J_PASSWORD variables, then open a new session, execute the Cypher statement and log the Director value of the first record.

Your console.log() statement should look similar to the code block below:

ts
console.log(res.records[0].get('Director'))

Copy the answer without any quotes or whitespace.

John Lasseter directed Toy Story.
