Python - Neo4j Failed to Connect but Scala Success

Same Connection (url, user and password) success when try using Scala. Unfortunately failed when using python with neo4j driver.

Python : Failed
driver = GraphDatabase.driver("bolt://127.0.0.1:7687", basic_auth={"neo4j","password"})

Scala : Success
val driver = GraphDatabase.driver("bolt://127.0.0.1:7687", AuthTokens.basic("neo4j","password"))

I got the following error using python :
neobolt.exceptions.AuthError: Unsupported authentication token, missing key scheme
Failed to write data to connection Address(host='127.0.0.1', port=7687) (Address(host='127.0.0.1', port=7687)); ("0; 'Underlying socket connection gone (_ssl.c:2067)'")

Any suggest how to solve this ?

Thank you

Hi
Did you manage to solve this?
The docs I've read suggest using auth=("neo4j",whatever_your_passsword_is_in_quotes) not basic_auth as you have here.
However - whenever I try this I get
neobolt.exceptions.AuthError: The client is unauthorized due to authentication failure.

Cheers

Same here.

I tried all variants of

NEO4J_URI = "bolt://localhost:7687"
# NEO4J_URI = "bolt://127.0.0.1:7687"

# driver = GraphDatabase.driver(NEO4J_URI, auth=("neo4j", "neo4j"))
# driver = GraphDatabase.driver(NEO4J_URI, auth=("neo4j", "password"))
driver = GraphDatabase.driver(NEO4J_URI)

Exception is:

same with python 3.9

I even get this error when I disable authentication
i.e.

# Whether requests to Neo4j are authenticated.
# To disable authentication, uncomment this line
# dbms.security.auth_enabled=true

Anybody any idea why this could happen?
