Indeed, it looks like it is compiled with 2.0.0-Beta5, but gateway isn't managing the version of the maven kotlin plugin.

Same issue occurred.

Use JDK 21, Spring Boot 3.2.4, Kotlin 1.9.23

Spring Cloude Depencencies 2023.0.0 works,
But 2023.0.1 occur at RouteDslKt

Fixed in 2023.0.2-SNAPSHOT

Any information, when 2023.0.2 will be released?
