  Check Buffer Item Configuration: Investigate the specific buffer item mentioned in the error message. Ensure that it is correctly configured and does not reference other items in a way that creates a cycle.
  Testing: After making changes, thoroughly test the rules to ensure that the error is resolved and that the logic behaves as expected.
