Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'some.other.property' in value "${some.other.property}"

I finally found the fix myself. Seems that the client bootstrapping doesn't occur automatically in new Spring Cloud release, instead we need to add following dependency and explicitly mention the bootstrapping in bootstrap.xml in the config-client.

Add the dependency

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

And then I just added the following line in bootstrap.xml of my config-client and it worked magically.

spring.cloud.bootstrap.enabled=true

I got this from this link:

Spring Cloud Config: client doesn't attempt to connect to the config server:

Thank you so much guys for your help and contribution! Thanks @Bragolgirith for the fix. Hope this helps people and save their time.
