This error indicates that there are multiple definitions or instances of the same view annotation, which can lead to conflicts or ambiguity in how the application is rendered or behaves.
  Cause:
  
  
  Duplicate Annotations: The most common cause of this error is that the same annotation is defined multiple times within the same context or scope. This can happen if:

  Incorrect Configuration: Sometimes, the error can arise from incorrect configuration settings in the application or the underlying data model.

  Identify Duplicates: Review the annotations in your application to identify where the duplicates are defined. This may involve checking:
  
  The metadata files (e.g., OData service definitions).
  The UI5 view files where annotations are applied.

  Remove the redundant annotation definitions.
  Consolidate them into a single definition if they are meant to represent the same functionality.
  
  
  
  Check for Conflicts: Ensure that there are no conflicting definitions in different parts of the application. If necessary, refactor the code to ensure that each annotation is unique and correctly defined.
