Using python driver to neo4j Standalone mode on k8s

[DonggookKim]

I want to use python driver to connect neo4j 3.5.22 that core-standalone mode on k8s.

Following this document(Using Neo4j from Python - Developer Guides), but I got error message like this.

Traceback (most recent call last):

    raise BoltRoutingError("Server does not support routing", address)
neo4j._exceptions.BoltRoutingError: Server does not support routing

During handling of the above exception, another exception occurred:

neo4j.exceptions.ServiceUnavailable: Server does not support routing

I know that standalone mode doesn't have routing table. But documents says using neo4j protocol.
What should I do?

Could you please show us your code that you are using to try and make the connection? Thanks!

[DonggookKim]

This is python code that I make the connection. Use py2neo lib, python 3.6.

    def create_genre_query(data, start_idx):
        print(start_idx)
        query = "MATCH (m:MOVIE {mcode:{mcode}})\n" + \
                "MATCH (g:GENRE {name:{genre_name}})\n" + \
                "MERGE (m)-[mgr:MOVIE_GENRE]->(g)\n" + \
                "MERGE (g)-[gmr:GENRE_MOVIE]->(m)\n"
        param = {}
        for idx, each in enumerate(data[start_idx:start_idx+1000]):
            genres = [x.strip() for x in each['genres'].split(',')]
            param['mcode'] = int(each['mcode'].strip())
            for genre in genres:
                graph = Graph(scheme='neo4j', host=neo4j_uri, port=port, user=id, password=passwd)
                param['genre_name'] = genre
                graph.run(query, param)

Thank you for your reply.

Are you using bolt://ip or bolt+routing://ip?

Additionally, there is some discussion in this thread that might be a good place to start diagnosing this problem.
