Specifically, it states that the value help view contains an element with an unsupported expression type. This typically occurs when the CDS view is trying to use a data type or expression that is not supported in the context of value help.
  Cause
  The error can be caused by several factors:
  
  Unsupported Data Types: The element in the value help view may be using a data type that is not supported for value help, such as complex types or certain calculated fields.
  Invalid Expressions: The expression used in the CDS view may not be valid for the context in which it is being used. For example, using aggregate functions or certain SQL expressions that are not allowed in value help.
  Incompatibility with UI5: If the value help is being used in a UI5 application, there may be incompatibilities between the data types expected by the UI5 framework and those defined in the CDS view.

  Check Data Types: Review the data types of the elements in the value help view. Ensure that they are compatible with value help. Commonly supported types include simple types like STRING, INTEGER, DECIMAL, etc.

  Modify the CDS View: If you identify any unsupported elements or expressions, modify the CDS view accordingly. You may need to create a new view or adjust the existing one to ensure compatibility.
  
  
  Test in Different Contexts: If the value help is being used in a specific application or context (like a UI5 app), test the CDS view in different contexts to see if the issue persists.
  
  
  Consult Documentation: Refer to the SAP documentation for Core Data Services and value help to understand the limitations and supported features.
