Setting common context path for flowable rest api in Spring Boot

I’m using Flowable 6.2.1 in a Spring Boot 1.5.9.RELEASE project.

I want to use the flowable-spring-boot-starter-rest-api and rest is working fine but can’t figure out how to change the context path of rest endpoints.
Maybe I’m wrong but it seems to me{somepath} put in file of the project should do exactly what I want. But it’s not working at all.

Can you give me any idea how to fix that?
