(Unable to retrieve routing information

Neo4j Graph Platform Installation
11

Just chiming in with another solution that helped me get around the "Unable to retrieve routing information" error when I moved from a local to an Aura connection.

I am able to use Python 3.8.1. I found that I needed to update my version of the neo4j module from 4.2.1 to 4.4.1.

I also found that at some stage during troubleshooting I had dropped "+s" from the "neo4j+s://" bit of the URI. Re-adding "+s" ultimately got me past the error.

Also really valuable for debugging is this snippet rouven.bauer posted:

from neo4j import GraphDatabase
from neo4j.debug import watch

uri = "..."
driver = GraphDatabase.driver(uri, auth=("neo4j", "password123"))

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()

That showed me the underlying "Connection to :7687 closed without handshake response" error, once I updated the neo4j module.
