•How to fix: You may need consider one or more of these steps to fix the issue:

• Ensure that event logging is enabled
• All JavaScript files are syntactically valid; otherwise exclude the respective files from the package
• Please note that you should uninstall all previous versions of the app before deploying
  Otherwise exclude the respective files from the package.
