  Transport or deployment issues where JavaScript resources were not properly deployed or got corrupted.
  Cache issues on the server or client side causing outdated or incomplete JavaScript files to be loaded.
  Authorization or access problems preventing the server from serving the JavaScript files.
  Server-side errors in the SAP Gateway or Web Dispatcher that interfere with serving static resources.

  Check the SAP System Logs and Traces:
  
  Use transaction ST22 to check for any short dumps related to the error.

  Clear the SAP Web AS cache using transaction /IWFND/CACHE_CLEANUP (for SAP Gateway).
  Restart the ICM or perform a cache refresh on the SAP Web Dispatcher if applicable.
  
  
  
  Check MIME Types and HTTP Headers:
  
  Ensure that the MIME types for .js files are correctly configured in the ICM profile parameters.
