• What is the cause and solution for SAP error message ESH_ENG_CDSVAL_ES045 - 'filteringAttribute': Empty object does not make sense (&1) ?

  The SAP error message ESH_ENG_CDSVAL_ES045 typically occurs in the context of SAP's Enterprise Search or when working with Core Data Services (CDS) views. This error indicates that a filtering attribute is being used in a way that is not valid, specifically that an empty object is being referenced, which does not make sense in the context of the operation being performed.
  Cause:
  
  Empty Filter Value: The error usually arises when a filter is applied to a CDS view or a search query, but the value being passed for that filter is empty or null.
  Incorrect Query Construction: The query might be constructed in such a way that it expects a value for a filtering attribute, but none is provided.
  Data Model Issues: There may be issues with the underlying data model or the way the CDS view is defined, leading to unexpected behavior when filtering.
  
  Solution:
  
  Check Filter Values: Ensure that the values being passed to the filtering attributes are not empty. Validate the input parameters before executing the query.
  Modify Query Logic: If the query is dynamically constructed, add logic to handle cases where filter values might be empty. You can either skip the filter or provide a default value.
  Review CDS View Definition: Check the definition of the CDS view to ensure that the filtering attributes are correctly defined and that they can handle null or empty values appropriately.
  Debugging: Use debugging tools to trace the execution of the query and identify where the empty value is being introduced. This can help pinpoint the source of the issue.
  Consult Documentation: Refer to SAP documentation for the specific version you are using to understand the expected behavior of filtering attributes in CDS views.
