debug.log

2023-03-03 14:28:38.956+0000 WARN [c.n.g.a.GdsFlightServer] The GDS Flight Server is enabled but the library is not licensed. The GDS Flight Server will not be started.

Solution

The above logging indicates that a GDS Enterprise license is not installed correctly. This is required as this feature is only part of Neo4j GDS Enterprise Edition and is not available in Neo4j GDS Community Edition. 

Neo4j GDS editions are documented on the following link:
