I have the same issue, is it as simple as changing the package here to tools.jackson ?

This blocks upgrading to Spring Boot 4 unfortunately

FWIW I forked the repo and made the suggested change and it works locally in my Kotlin project
I'll raise a PR - just jumping through necessary hoops internally
