@sp-yang can you provide more details on what's not working? I'm don't think we use any EE only features right now. Most of the work is done in the python code anyhow.

@jexp For example, in backend/src/graphDB_dataAccess.py, the function check_account_access() uses command "
SHOW USER PRIVILEGES
YIELD *
WHERE graph = $database AND action IN ['read']
RETURN COUNT(*) AS readAccessCount",
which is only supported by Neo4j EE version. CE version will throw an exception.

CE version will throw an exception.

I have the same error message with the current version. When I revert to a working tree that has the previous version, no errors.

I agree this would be nice to have! I suspect maybe it's somehow inferring that the user doesn't have edit permissions in the community edition, because the roles show as null, but in reality, per this documentation, "In Neo4j Community Edition there are no roles, but all users have implied administrator privileges."

Good point. This is a recent addition that we can fix.

The workaround is just return true when Exception occured.

        query = """
        SHOW USER PRIVILEGES 
        YIELD * 
        WHERE graph = $database AND action IN ['read'] 
        RETURN COUNT(*) AS readAccessCount
        """
        try:
            logging.info(f"Checking access for database: {database}")

            result = self.graph.query(query, params={"database": database})
            read_access_count = result[0]["readAccessCount"] if result else 0

            logging.info(f"Read access count: {read_access_count}")

            if read_access_count > 0:
                logging.info("The account has read access.")
                return False
            else:
                logging.info("The account has write access.")
                return True

        except Exception as e:
            logging.error(f"Error checking account access: {e}")
            return True # False

are you using the CE version deployed locally?
