Specifically, the error message states that the response field &1 does not exist. This typically occurs in the context of SAP Enterprise Search or when working with the Object Model in SAP.
  Cause:
  
  Field Mismatch: The specified response field in the URL does not match any of the fields defined in the data model or the response structure. This could be due to a typo, a field that has been removed, or a field that has not been properly defined in the system.
