I have been running Neo4J V 3.5.19 with this docker script
docker run \
--publish=7474:7474 --publish=7687:7687 \
--volume=$HOME/neo4j/data:/data \
--volume=$HOME/neo4j/logs:/logs \
--env NEO4JLABS_PLUGINS='["apoc"]' \
--env NEO4J_AUTH=neo4j/test \
--name=neo4j \
--restart=always \
--detach \
neo4j:3.5.19
I was eventualy able to get 4.1 working with this script.
docker run \
-p 7474:7474 -p 7687:7687 \
--volume=$HOME/neo4j/data:/data \
--volume=$HOME/neo4j/logs:/logs \
--volume=$HOME/neo4j/plugins:/plugins \
-e NEO4J_apoc_export_file_enabled=true \
-e NEO4J_apoc_import_file_enabled=true \
-e NEO4J_apoc_import_file_use__neo4j__config=true \
-e NEO4JLABS_PLUGINS=\[\"apoc\"\] \
--env NEO4J_AUTH=neo4j/test \
--name=neo4j \
--restart=always \
--detach \
neo4j:latest
The Neo4j Browser is working fine, but I'm unable to connect from my app or the graphql playground. The same error is thrown in both places.
"code": "INTERNAL_SERVER_ERROR",
"exception": {
"code": "ServiceUnavailable",
"name": "Neo4jError",
"stacktrace": [
"Neo4jError: connect ECONNREFUSED 192.168.0.200:7687",
If I go back to the original v3.5 docker script everything works again.
Any ideas?
I know that for me when I made the switch over to 4.0 when I created the driver I had to add:
const driver = neo4j.driver(
neo4jURI,
neo4j.auth.basic(
neo4jUser,
neo4jPassword
),
{
encrypted: development ? "ENCRYPTION_OFF" : "ENCRYPTION_ON"
}
);
This encryption flag. That may be your issue.
It didn't like that I'm afraid.
.../dev/grand-stack/api/build/index.js:33
encrypted: development ? "ENCRYPTION_OFF" : "ENCRYPTION_ON"
^
ReferenceError: development is not defined
Do I need to update other packages by any chance?
Development is a local environment variable for me. You'll just need to pass encrypted as on, so:
const driver = neo4j.driver(
neo4jURI,
neo4j.auth.basic(
neo4jUser,
neo4jPassword
),
{
encrypted: "ENCRYPTION_ON"
}
);
For local development I didn't need encrypted set to true for my aura instance I did.
I made the change. The Neo4j browser runs, and the GraphQL server starts without errors.
My app and the Playground both return:
"extensions": {
"code": "INTERNAL_SERVER_ERROR",
"exception": {
"code": "ServiceUnavailable",
"name": "Neo4jError",
"stacktrace": [
"Neo4jError: socket hang up",
Can you post the code you're using to create your driver, server, etc? A github link something like that would help.
Here is index.js
import { ApolloServer } from "apollo-server-express";
import { typeDefs, resolvers } from "./graphql-schema";
import express from "express";
import { v1 as neo4j } from "neo4j-driver";
import { makeAugmentedSchema } from "neo4j-graphql-js";
import dotenv from "dotenv";
dotenv.config();
const app = express();
const schema = makeAugmentedSchema({
typeDefs,
resolvers,
});
const driver = neo4j.driver(
process.env.NEO4J_URI || "bolt://localhost:7687",
neo4j.auth.basic(
process.env.NEO4J_USER || "neo4j",
process.env.NEO4J_PASSWORD || "test"
),
//added the following for neo4j v4.1 July 2020
{
encrypted: "ENCRYPTION_ON"
}
);
const server = new ApolloServer({
context: { driver },
schema: schema,
introspection: true,
playground: true
});
const port = process.env.GRAPHQL_LISTEN_PORT || 4001;
const path = "/graphql";
server.applyMiddleware({app, path});
app.listen({port, path}, () => {
console.log(`GraphQL server ready at http://localhost:${port}${path}`);
});
Hello @r.chevalier335 i am facing the same issue, did you find a solution ?
Sadly, not I did not find a solution. I gave up, so I am still using version 3.5.19.
Hello, @r.chevalier335, it's working for me now, I am using the version 4.0.9 of neo4j, but instead of using NEO4_URI ="bolt://localhost:7687" I am using "neo4j://localhost:7687", and I am building the Neo4j container from docker-compose.yml file because I tried with the docker run command, but it gave me errors, so try with docker-compose maybe it will solve your problem 
Thank you. I will give it a try.
