Hi I am trying to deploy a Spring Boot Application to Heroku. The build is a success but when I try to run the app I get a Status 503: Service Unavailable Error. I referred a similar post Application Error after a successful deployment at Heroku but this didn’t helped me. Here is my pom.xml 4.0.0 org.springframework.boot spring-boot-starter-parent 2.5.2 com.sample.app
