Although Lombok @Data(staticConstructor="of") is able to produce code that compiles, builds the application successfully and allows it to run, there appears to be a syntax error reported by IntelliJ with regards to the method.

edit

This can happen if your IntelliJ version is not up to date or if the Lombok plugin is not properly installed or configured. Try updating your IntelliJ version and make sure the Lombok plugin is installed and enabled. If the issue persists, you can also try adding the Lombok jar to your project manually, or adding the following line to your build.gradle file:

annotationProcessor "org.projectlombok:lombok:1.18.20"
