Failed creating nodes to neo4j aura

[ppalka-lingaro]

Expected Behavior (Mandatory)

Connect to neo4j aura and creation of nodes and relationship using neomodel
not get any error
config.DATABASE_URL = 'neo4j+s://{}:{}@{}'.format(user, password, uri)
neo4j+s://neo4j:password@aura_instance.databases.neo4j.io:7687

Actual Behavior (Mandatory)

writing or connection failed
ERROR:
after 1st execution
Failed to write data to connection ResolvedIPv4Address(('XX.XX.XX.XX', 7687)) (ResolvedIPv4Address(('XX.XX.XX.XX', 7687)))
Failed to write data to connection IPv4Address(('aura_instance.databases.neo4j.io', 7687)) (ResolvedIPv4Address(('XX.XX.XX.XX', 7687)))

after second execution, looks that nodes where created but why after 1st time it's failing with this error
neomodel.exceptions.UniqueProperty: Node(1381) already exists with label Person and property name = 'John'

How to Reproduce the Problem

1. create aura instance on neo4j page
2. connect using neomodel

Simple Example

class Person(StructuredNode):
name = StringProperty(unique_index=True)
knows = RelationshipTo('Person', 'KNOWS')

john = Person(name='John').save()
jane = Person(name='Jane').save()

Create a relationship

john.knows.connect(jane)

Datasets and Statements

I tested connection using
cypher-shell -a neo4j+s://aura_instance.databases.neo4j.io -u neo4j -p password
Connected to Neo4j using Bolt protocol version 5.3 at neo4j+s://aura_instance.databases.neo4j.io:7687 as user neo4j.

also before was using native neo4j driver and all was working

Screenshots (where it's possible)

Specifications (Mandatory)

• OS: Windows 11
• Library: neomodel 5.2

Hello,

From your message, I get you did manage to connect to Aura using neomodel, right ? It's writing the node that is causing issues.
Also, we do test connection to Aura in our integrations test, with all four available protocols, and all supported Python versions 3.7 -> 3.11 (note we do not support Python 3.12 yet)

Just in case, can you add this in your code, before trying to connect ?

from neo4j.debug import watch
with watch("neo4j"):
    # Connect and query

This should output more information about the driver status
