I am upgrading my spring boot App from 1.5.0 to 2.0.0. After upgrade I am unable to read vault config from bootstrap.yml

My config as follows

   spring:
      vault:
      enabled: true
      authentication: TOKEN
      host: ${VAULT_ADDR:localhost}
      port: ${VAULT_PORT:8200}
      token: ${VAULT_TOKEN:eafaa220-901acaafffb5}
      scheme: http

and my build.gradle dependencies

springBootVersion = '2.0.9.RELEASE'
springCloudVersion = 'Finchley.SR4'

 compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework.boot:spring-boot-starter-actuator')
compile('org.springframework.boot:spring-boot-configuration-processor')
compile('org.springframework.boot:spring-boot-starter-hateoas')
compile('org.springframework.cloud:spring-cloud-starter-consul-config')
compile('org.springframework.cloud:spring-cloud-starter-netflix-hystrix')
implementation('org.springframework.cloud:spring-cloud-starter-vault-config')

While starting the app in local I am getting below exception

***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to bind properties under 'spring.cloud.vault' to org.springframework.cloud.vault.config.VaultProperties:

    Reason: HV000030: No validator could be found for constraint 'javax.validation.constraints.NotEmpty' validating type 'java.lang.String'. Check configuration for 'host'

Action:

I am not sure what is missing and appreciate any help
