  Review the Filter Expression: Check the filter expression in your OData request. Ensure that it only uses supported operators and fields. Refer to the OData service documentation for the supported filter syntax.
  Modify the Query: Simplify the filter by removing unsupported parts or breaking it down into multiple requests if necessary.
  Check Service Implementation: If you have access to the service implementation, review the code to ensure that it correctly handles the filter expressions being sent.
