  Cause:
  This error typically occurs in the context of using the SAP Gateway or OData services when:
  
  The property path specified in a query or service call does not begin with the expected "Parameters" entity type.
  There may be a misconfiguration in the OData service or the way the query is constructed.

  Review the Query Structure:

  /YourService/Parameters(YourParameterValue)/YourProperty
  
  
  
  
  Check for Typos or Syntax Errors:
  
  Look for any typos or syntax errors in the property path you are using. Ensure that it matches the expected format.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific OData service you are using to understand the expected structure and parameters.
