This error indicates that a required key field for a node in a data model is missing or not properly specified.
  Cause:
  
  Missing Key Fields: The error usually arises when a request is made to access a node in the data model, but the key fields that uniquely identify the record are not provided or are incomplete.

  Inspect Data Model: Review the data model configuration in the SAP system to ensure that the key fields are correctly defined for the relevant nodes.
  Debugging: If you have access to the backend, you can use transaction codes like SE80 or SE11 to check the structure of the data model and confirm that the keys are correctly set up.
