This error indicates that there is an issue with the data source or the way fields are being accessed in a CDS view.
  Cause:
  
  Unsupported Field Path: The error suggests that the field path you are trying to access is not supported for the specified source type. This could be due to the way the CDS view is defined or the underlying data model.
  Incorrect Data Source: The source type specified in the error message may not be compatible with the field path you are trying to use. This can happen if the data source is not properly defined or if it does not contain the expected fields.
  Changes in Data Model: If there have been recent changes to the underlying data model or the CDS view, it may lead to inconsistencies that trigger this error.

  Adjust Field Paths: If the field paths are incorrect, modify them to align with the available fields in the data source. You may need to refer to the documentation or data model to find the correct field paths.
  Check for Updates: If you are working in a development environment, ensure that you have the latest updates and that there are no pending transports that could affect the data model.
