Exakat : @ 2014-2023 Damien Seguy - Exakat SAS <contact(at)exakat.io>.
Version : 2.6.0 - Build 1483 - Mon, 09 Oct 2023 14:31:20 +0000
I used tinkerpop from https://archive.apache.org/dist/tinkerpop/3.4.12/apache-tinkerpop-gremlin-server-3.4.12-bin.zip
I have also tried version 3.7.0 and version 3.4.14.
I did the "optional" neoj4 install.
I tried the troubleshooting steps listed here https://exakat.readthedocs.io/en/latest/Administrator/Installation.html#installation-on-osx
