  The SAP error message /UI5/APP_API055 Node with Path &1 does not exist typically occurs in the context of SAP Fiori applications that utilize the UI5 framework. This error indicates that the application is trying to access a node in the OData model that does not exist or is not available at the specified path.
  Causes:
  
  Incorrect Path: The path specified in the application code may be incorrect or malformed, leading to an attempt to access a non-existent node.
  Data Not Loaded: The data that the application is trying to access may not have been loaded yet, possibly due to asynchronous loading or timing issues.
  Backend Issues: There may be issues with the backend service, such as the OData service not being available, or the data not being returned as expected.
  Authorization Issues: The user may not have the necessary permissions to access the data at the specified path.
  Model Binding Issues: The model may not be properly bound to the view, leading to the application not being aware of the available nodes.
  
  Solutions:
  
  Check the Path: Verify that the path specified in the application code is correct. Ensure that it matches the structure of the OData service.
  Inspect the OData Service: Use tools like the SAP Gateway Client or Postman to test the OData service directly. Check if the expected data is being returned and if the node exists.
  Debugging: Use the browser's developer tools to debug the application. Check the network requests to see if the OData service is being called correctly and if the response contains the expected data.
  Check Model Binding: Ensure that the OData model is correctly instantiated and bound to the view. Verify that the model is set up properly in the controller.
  Authorization Check: Ensure that the user has the necessary authorizations to access the data. Check the roles and permissions assigned to the user.
  Error Handling: Implement error handling in the application to gracefully manage situations where data is not available.
