Hi
I'm new to neo4j and have been playing around with the community version for a while. Creating queries, adding visualizing data and importing from csv works fine.
When I try to add Graph Data Science library according to the guide, however, I get an error and the server does not start.
I downloaded the jar file from here https://neo4j.com/download-center/#algorithms, put it in the plugin folder, added the two lines
dbms.security.procedures.unrestricted=gds.*
dbms.security.procedures.allowlist=gds.*
in /conf/neo4j.conf
and started the folder.
I got the following error messages:

Graph Data Science version: neo4j-graph-data-science-1.6.1
Is GDS not availible for community, or did I miss anything during the installation?
Thank you for any help.

I've not setup neo4j on windows like you are doing (normally I run neo4j inside docker on ubuntu, or for quick simple work maybe the neo4j client), but have a couple of questions
can you share the rest of the config file and how you are starting/running neo4j?

I didn't configure the path anywhere explicitly, but just added the plugin in the plugins folder as described in the instructions. The extra forward slash at the beginning seems to be something the debug logs adds by itself. The whole pathname is enclosed in backticks as well, but it seems the forum here formats them and makes the text yellow instead.
I never tried with any other plugins. Will try looking up another one and add them.
