Index page doesn't work but api works on AWS beanstalk Sprint Boot

I am trying to deploy a spring boot application to aws.

I changed the port to 5000 via application.properties
Now, url/api/hello works fine but url/ doesn't work

url/api/hello

url/

I am getting a white label error.

package com.example.package-name;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;

@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan()
public class DemoApplication extends SpringBootServletInitializer

public static void main(String args)
SpringApplication.run(DemoApplication.class, args);

Can anyone tell me how to fix this?
Is there anything wrong with the main Starter file?

Note: Everything works fine locally, the error page is loading instead
of index page only in AWS

I assume you deploy in aws elastic beanstalk tomcat server, please make sure access via beanstalk URL which will give you after uploading jar/war, generally whitespace error gives you whenever you try to access wrong URL/wrong parameters, if possible provide details with screenshots.
