Hi nikhilhill19,

The zip file provided results in an empty JavaScript file.

However, there is a common scenario why this may happen, if you’re running a React application with Strict mode, the app technically renders each component twice. This isn’t a concern when you build your application, only when you’re developing, however, you can disable that. (If this is the case you’re seeing)

Best regards,
Tyler
