I've created a google cloud VM instance with neo4j on it, by following this instructions: https://neo4j.com/docs/operations-manual/current/cloud-deployments/neo4j-gcp/single-instance-vm/
The browser Db looks fine: I can view and manipulate from the browser.
The problem is when trying connecting neo4j from nodejs using neo4j-driver npm.
I keep getting this error:
UnhandledPromiseRejectionWarning: Neo4jError: Connection was closed by server
this is the code:
const neo4j = require('neo4j-driver')
const uri = 'bolt://[EXTERNAL_IP]:[PORT]'
const user = 'USER_NAME'
const password = 'PASSWORD'
const createPerson = async () => {
const driver = neo4j.driver(uri, neo4j.auth.basic(user, password), { encrypted : "ENCRYPTION_OFF"})
const session = driver.session()
const personName = 'Bob'
try {
const result = await session.run(
'CREATE (a:Person {name: $name}) RETURN a',
{ name: personName }
)
const singleRecord = result.records[0]
const node = singleRecord.get(0)
console.log(node.properties.name)
} finally {
await session.close()
}
// on application exit:
await driver.close()
}
createPerson()
The code is taken from this link: https://neo4j.com/developer/javascript/
I run this command: gcloud compute ssh my-neo4j-instance in GCP shell, in hope that maybe adding ssh would solve the issue but it didn't.
changing the driver encrypted options to false also didn't help.
Console logging the error print this:
Neo4jError: Connection was closed by server
