After disabling Spring Auto Reconfiguration, application is not able to connect to config server(this leads to placeholder resolve problem)

[dev-praveen]

We have a spring boot application that is deployed in PCF and works fine until we tried to migrate it to java-cfenv-boot library by following the migration guide and removing the dependencies it suggests. However, we encounter a problem with the centralized configuration. The application fails to get the placeholder values from the Spring Cloud Config Server (bound to PCF). This is the error we get: [OUT] Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder ‘some.value’ in value “${some.value}”

removed org.springframework.boot:spring-boot-starter-cloud-connectors or org.springframework.cloud:spring-cloud-core org.springframework.cloud:spring-cloud-connectors-core org.springframework.cloud:spring-cloud-cloudfoundry-connector org.springframework.cloud:spring-cloud-spring-service-connector dependencies from pom file

added

io.pivotal.cfenv java-cfenv-boot 2.4.0 dependency spring.profiles.active: dev,cloud JBP_CONFIG_SPRING_AUTO_RECONFIGURATION: '{enabled: false}'

please help us why after removing recommended dependencies from the documentation application is not able to locate the real config server.
