@CircuitBreaker not working on method inside spring boot service

[tuanlinh281]

Resilience4j version: 1.7.1

Java version: 17

Spring boot version: 2.3.12.RELEASE

I'm having the configuration in yaml file like this
resilience4j:
circuitbreaker:
instances:
testService:
slidingWindowSize: 100
permittedNumberOfCallsInHalfOpenState: 10
slidingWindowType: TIME_BASED
minimumNumberOfCalls: 20
waitDurationInOpenState: 50s
failureRateThreshold: 50
slowCallRateThreshold: 50
slowCallDurationThreshold: 50s
and pom file with resilience4j-spring-boot2, resilience4j-circuitbreaker, spring-boot-starter-aop, spring-boot-starter-actuator, spring-boot-starter-web dependencies.
I'm putting the annotation on the service's method process()
@CIRCUITBREAKER(name = "testService", fallbackMethod = "onFailure")
and I define method onFailure with parameters like method process() plus parameter Throwable.
Inside process() method I use Thread.sleep() to delay the response in 70s but the fallback method is not invoked. Could somebody please check for me?
