Error: compat is required

Thanks for this amazing plugin, unfortunately I tried the docker command that you have mentioned but with graph-data-science being added into the plugin list and this is the error that I am getting:

Could you please confirm which version of DozerDB you're using?

Also, are you using the graph-data-science plugin we compiled or the one from the Neo4j GitHub repo? This will help us troubleshoot the issue.

Unfortunately, Neo4j's setup currently defaults to the commercial version of the graph-data-science plugin, even for the community edition. We may need to recompile the plugin for each Neo4j version if this continues.

Let me know your DozerDB version, and I'll figure out the next steps.

Thank you.

Sure, I was using the dozerdb 5.20.0 alpha version. Well for the plugin, I downloaded and added the plugin to the plugins as mentioned in the README.md file and while starting the docker container I added graph-data-science aside from apoc into the NEO4J_PLUGINS list.
