Question

I try to deploy my Vaadin Springboot application and it worked perfectly on localhost but when tried to deploy it with heroku i kept getting the H10 error code.

here are the heroku error logs

Procfile

web: java $JAVA_OPTS -jar server/webapp-runner.jar --port $PORT target/*

I did not find any answers on stackoverflow, that would solve my problem.

Answer 1

You are using Spring Boot and don't need the webapp-runner!

Please read the docs: https://devcenter.heroku.com/articles/deploying-spring-boot-apps-to-heroku
