  Duplicate Text Keys: The most common cause of this error is that the same text key (name) is defined more than once in the resource bundle files (e.g., i18n.properties).
  Multiple Resource Bundles: If your application is using multiple resource bundles, there might be overlapping keys across these bundles.
  Incorrect Merging: If you are merging or concatenating resource bundles incorrectly, it can lead to duplicate keys.
  
  Solution:
  
  Identify Duplicates: Check the resource bundle files (e.g., i18n.properties) for the specified text key (&1) and ensure that it is defined only once. You can use text search tools or IDE features to find duplicates.
  Remove or Rename: If you find duplicate entries, you can either remove the duplicates or rename them to ensure that each key is unique.
  Check All Resource Bundles: If your application uses multiple resource bundles, check all of them for the duplicate key.
  Rebuild the Application: After making changes to the resource bundles, rebuild and redeploy your application to ensure that the changes take effect.
  
  Related Information:
  
  Resource Bundles: In SAPUI5, resource bundles are used for internationalization (i18n) and contain key-value pairs for text used in the application.
  Best Practices: To avoid such issues in the future, follow best practices for managing resource bundles, such as:
  
  Use a consistent naming convention for keys.
  Regularly review and refactor resource bundles to remove unused or duplicate keys.
  Utilize tools or scripts to check for duplicates in resource bundles during development.
