Issue connecting to Noe4j Aura with Python 'neo4j' driver

Question

I attempted to connect neo4j aura database using Python but failed as "Unable to retrieve routing information".

from neo4j import GraphDatabase
from neo4j.debug import watch

uri = "neo4j+s://<id>.databases.neo4j.io"
driver = GraphDatabase.driver(uri, auth=("neo4j", "<password>"))

def workload(tx):
    return tx.run("RETURN 1 as n").data()

with watch("neo4j"):  # enable logging
    with driver.session() as session:
        session.write_transaction(workload)

driver.close()

Running above python scripts returned the following log:

I looked into neo4j documentation and searched other places but none of the possible resolutions can be found.

Version: Python 3.7.4 neo4j 4.4.2

I very much appreciate your input if you have ever experienced the same issues and found any way to resolve the issue.
