Simple App starter for Vaddin14 not worked


I downloaded Simple App starter for Vaadin 14 to try. However, I found that the Reviews part doesn’t work. Any advices of how to fix?

Many thanks,

Try updating to <vaadin.version>14.0.0.rc2</vaadin.version> in your pom.xml, delete the files package.json and package-lock.json, run mvn clean and then start again. That fixed the issue for me.
