Hi @10000-ki , if I take a look on this:
https://github.com/operator-framework/josdk-spring-boot-starter/blob/v5.2.0/pom.xml
the problem seems to that you are using newer version that than Java Operator SDK, there is 6.7.2 while you are using 6.8. This is probably the problem.

oh i see.. i will upgrade josdk spring boot starter version thx
