can anyone please help me fix this error.

Hello @percyjay1998 ,
the issue is likely in the configuration.
The error message tells you its part of the dbms.security.procedures.unrestrictedsetting.
it should be `dbms.security.procedures.unrestrictedsetting=gds.*.

see our docs for more details on how to install GDS correctly

Hi @florentin_dorre ,
I did that too. But still getting the same error.

dbms.security.procedures.unrestricted=jwt.security.*,apoc.*,gds.*

dbms.security.procedures.allowlist=apoc.coll.*,apoc.load.*,gds.*

Just an additional information I am running the neo4j on the docker.

for the docker setup i use the following environment vars to apply the settings correctly:

      - NEO4J_PLUGINS=["graph-data-science"]
      - NEO4J_dbms_security_procedures_allowlist=gds.*
      - NEO4J_dbms_security_procedures_unrestricted=gds.*

how did you change the settings?

actually, --env NEO4J_PLUGINS='["graph-data-science"]' as shown in Neo4j on Docker - Neo4j Graph Data Science should be enough
