Answer 1 · 2021-07-02T11:19:06.000Z

Generally speaking - always look at last caused by:
Connection refused: localhost/127.0.0.1:7687
Either there's nothing listening (dbms not started) or there's something in between getting in the way. Hardly anything gets in the way to localhost, unless it's something virtualised/containerized.

I've discovered in the meantime that auto-index=update isn't going to work, has to be =assert.

Answer 2 · 2021-07-02T11:38:42.000Z

@jalmasi my mistake I pasted the wrong error log (I took an error log from when neo4j was stopped)

here's the error log when neo4j is running, the error is no longer about connecting to localhost

Answer 3 · 2021-07-02T11:52:29.000Z

Haven't seen this one, but please git pull first and use dbms branch.
spring.data.neo4j.auto-index=update
has to be
spring.data.neo4j.auto-index=assert

Answer 4 · 2021-07-02T12:47:34.000Z

I just did that (dbms branch with auto-index=assert), same error:

Dang, I have no idea how to reproduce this.
Provide some more info, OS, DB etc versions?
How exactly did you build and start vrspace server?

Answer 6 · 2021-07-02T14:31:10.000Z

OS: Linux DB: Neo4J 4.3.1 Java: OpenJDK 11 I just opened VRSpace server in the IDE (IntelliJ IDEA) tweaked applicaton.properties and hit "play" which starts at "org.vrspace.server.ServerApplication". Maybe we can look at it together sometime?

Yes we should. I don't have any meetings today, ping me whenever you're ready.

Answer 8 · 2021-07-12T11:25:24.000Z

Neo4j libraries used work up to version 4.2.5. Updated libs, tested with 4.3.2, seems to work fine.

Answer 9 · 2021-07-12T12:28:19.000Z

@jalmasi appears to be working :)

will you merge to master?

Answer 10 · 2021-07-12T16:23:46.000Z

Great!
Merging right away
