I'm trying to use py2neo to query a Neo4J database. I can create a graph object to connect to the database, but when I try to run a query, I get an error:
py2neo.packages.neo4j.v1.exceptions.ProtocolError: Server responded HTTP. Make sure you are not trying to connect to the http endpoint (HTTP defaults to port 7474 whereas BOLT defaults to port 7687)
I'm not sure if there's an issue with the server set up or if I'm just missing some parameter I need to set to get everything working.
Here's the code I'm using:
from py2neo import Graph
graph = Graph("bolt://bolt.bump.dev.stratified:80", auth=("neo4j", "bump"), bolt=True)
data = graph.run("MATCH p=()-[r:ACTED_IN]->() RETURN p LIMIT 25").data()
FWIW, I've also tried
graph = Graph("bolt://bolt.bump.dev.stratified:7687", auth=("neo4j", "bump"), bolt=True)
data = graph.run("MATCH p=()-[r:ACTED_IN]->() RETURN p LIMIT 25").data()
And here's the full error message (received for either port):
