neosemantics graphapp for Neo4j 5.11.0 hangs on startup

[emetsger]

Hello!

I'm using Neo4j 5.12.0 and am unable to run the neosemantics 5.11.0.0 release (the rdf endpoint responds, but the desktop hangs trying to find the plugin). When I add n10s to NEO4J_PLUGINS, the server startup complains:

Fetching versions.json for Plugin 'n10s' from https://neo4j-labs.github.io/neosemantics/versions.json
ERROR: No compatible "n10s" plugin found for Neo4j 5.12.0.
This can happen with the newest Neo4j versions when a compatible plugin has not yet been released.
You can either use an older version of Neo4j, or continue without n10s.
Neo4j will continue to start, but "n10s" will not be loaded.

Any chance a neosemantics 5.12.0.0 release could be whipped up? 🙏

In the meantime, I plan to downgrade to Neo4j 5.11. ✅

Ok, after downgrading to 5.11, the neosemantics desktop app still hangs, so this may not be related to version compatibility.

• Neo4j 5.11
• Neosemantics graphapp version 0.3.4
• n10s RDF endpoint is pingable
• SHOW PROCEDURES lists a number of n10s.* procedure names

See the linked screencap for the desktop client behavior

Ok, I see: the graphapp only supports Neo4j 4.3 and 4.4, but the procedures should still be executable. Got it.
