Unable to instantiate CloudFoundryVcapEnvironmentPostProcessor during config refresh

Before adding and provisioning spring cloud vault, our app was refreshing fine via the /actuator/refresh endpoint. But after adding and provisioning spring cloud vault the endpoint returns 500 due to the following exception:

java.lang.IllegalArgumentException: Unable to instantiate org.springframework.boot.cloud.CloudFoundryVcapEnvironmentPostProcessor. Caused by: java.lang.ClassNotFoundException: org.springframework.boot.cloud.CloudFoundryVcapEnvironmentPostProcessor

Our app's dependency versions:

• spring boot 4.0.6
• spring-cloud-dependencies: 2025.1.0
• spring-cloud-services-starter-config-client: 4.4.0
• spring-cloud-starter-vault-config: 5.0.0
• spring-vault-core: 5.0.0
• spring-boot-starter-cloudfoundry

The rest of the stack trace:

Start with the /actuator/refresh entry point and the ConfigDataContextRefresher and ContextRefresher stack frames, then inspect the listed Spring Boot, Spring Cloud Vault, and Cloud Foundry dependencies for the missing class. Reproduce the refresh failure and determine the compatible dependency configuration; done means /actuator/refresh completes without the ClassNotFoundException and returns successfully.
