Blank screen

I tried to fix this problem by myself, but i just gave up. Before making 'mvn spring-boot:run', i made 'mvn install -U compile' (end up successful) in project root directory, then 'cd hybrid.... && mvn install -U compile && mvn spring-boot:run' . Console prints out:

And this issue persists in Chrome / Firefox

Any suggestions how to solve this?

I'm having the same problem!

[der-ali]

commenting "server.context-path=/demo" in application.properties will solve the problem ;)
