GraphFactory could not instantiate this Graph implementation #3574

Open Simkiw opened 1 year ago

Simkiw commented 1 year ago

JanusGraph Version: 0.6.2
TinkerPop Version: 3.5.3

My container used to be working fine :)
And for some reason, it crashed. Is it because I did not well configure the proxy, is it because i was trying to run queries while the container was still on setup phase? I don't know, and I don't much about graphs or thinkerpop. I hope the scenario would be enough to understand the issue along with the error

Hello @Simkiw, this seems like a configuration problem. The error message does not contain much information. Could you maybe share the (redacted) content of /etc/opt/janusgraph/janusgraph-server.yaml and /etc/opt/janusgraph/janusgraph.properties?
