  The SAP error message /UI5/THEMING_MSGS013 Missing or wrong route to theming service in neo-app.json of SCP app &1 indicates that there is an issue with the configuration of the theming service in the neo-app.json file of your SAP Cloud Platform (SCP) application. This error typically arises when the application cannot find the correct route to the theming service, which is essential for applying custom themes to your UI5 application.
  Cause
  The error can be caused by several factors:
  
  Missing Route: The neo-app.json file does not contain a route to the theming service.
  Incorrect Route: The route defined in the neo-app.json file is incorrect or does not match the actual service URL.
  Service Not Deployed: The theming service may not be deployed or available in the SCP environment.
  Configuration Issues: There may be other configuration issues in the neo-app.json file that prevent the application from accessing the theming service.
  
  Solution
  To resolve this error, follow these steps:
  
  
  Check neo-app.json:
  
  Open the neo-app.json file in your application.
  Ensure that there is a route defined for the theming service. It should look something like this:
  
  {
    "routes": [
      {
        "path": "/theming",
        "target": "theming"
      }
    ]
  }
  
  
  Define Target:
  
  Ensure that there is a corresponding target defined for the theming service in the neo-app.json file:
  
  {
    "targets": {
      "theming": {
        "type": "destination",
        "name": "your_theming_service_destination"
      }
    }
  }
  Replace your_theming_service_destination with the actual destination name configured in your SCP.
  
  
  Check Destination Configuration:
  
  Go to the SAP Cloud Platform cockpit and check the destination configuration for the theming service. Ensure that it is correctly set up and points to the right service URL.
  
  
  
  Deploy the Theming Service:
  
  If the theming service is not deployed, you may need to deploy it. Check the service availability in your SCP account.
  
  
  
  Test the Route:
