what version are you using? I was able to get it working with version 5.23 (the extended apoc jar is not posted for 5.24). ![Screenshot 2024-10-22 at 4.58.57 AM](https://us1.discourse-cdn.com/flex021/uploads/neo4jcommunity/original/3X/9/3/93aa69c9b86ece206fdefddd4ed8a669270ee7e4.png) ![Screenshot 2024-10-22 at 4.58.32 AM](https://us1.discourse-cdn.com/flex021/uploads/neo4jcommunity/original/3X/a/d/adc0250819deac0f43fd4a0687c9ba5733fe401c.png) ---

I did not find an apoc extended jar for 5.24. Where did you get it? ---

I found the repo on GitHub, but I did not find an artifacts section where I usually download the jar. Did you find it or did you build it yourself? ---
