logback-spring. is unable to read property value from application.yml-CodePudding

My logback-spring.xml reads fine from application.properties but not from application.yml. In my project, we have been asked to only use the YAML format as this format is being used in other microservices within the same project, so I cannot add propertes file. please help me why my application.yml is not read in logback.xml

I have tried variety of ways and searched similar questions on stackoverflow but no question has correct answer**. please dont mark this as duplicate**.

Above is my logback-spring.xml. Please refer my application.yml below:-

  application:
    name: Logbacking-service

You can use below in your logback file as explained in the docs

If you enable trace logging level in your logback for "org.springframework.core.env.PropertySourcesPropertyResolver" you will see the location of application.yml from where it reads the properties. This will help you understand from where the spring boot is trying to find configuration. Something like below

Searching for key 'spring.profiles.active' in PropertySource 'applicationConfig: [classpath:/application.yml]
