Spring boot app access to Azure Keyvault secret - spring-boot

Question

I am trying to set up a Spring boot app to connect to Azure keyvault and fetch secrets.
I have looked across various code samples, but cannot get one to work.
There are no errors related to the keyvault library itself, but the Spring bean does not get initialized with the property fetched from the secret.
I am using Spring boot 2.7.3 and the keyvault starter lib is 4.2.0. This is what I referred to get my property config.
https://microsoft.github.io/spring-cloud-azure/4.2.0/reference/html/appendix.html#_azure_key_vault_secrets_properties
application.yml
------------
spring:
cloud:
azure:
keyvault:
secret:
enabled: true
endpoint: https://uri/
credential:
client-certificate-path: <path to pem file>
client-id: <client-id>
profile:
tenant-id: <tenant-id>
build.gradle
--------------
implementation 'com.azure.spring:spring-cloud-azure-starter-keyvault-secrets:4.2.0'
Spring bean
-------------
#Configuration
#Getter
#Setter
public class AKVProperties {
#Value("${MYAPP-DB-LOGIN-PASSWORD}")
private String dbPassword1;
...
Exception at startup:
----------------------
Error creating bean with name 'AKVProperties': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'MYAPP-DB-LOGIN-PASSWORD' in value "${MYAPP-DB-LOGIN-PASSWORD}"

I think the issue is with application.yaml file. you have to set your config settings under property-sources: .
This is the application.yaml I used where everython is set under the property-sources:
spring:
cloud:
azure:
keyvault:
secret:
property-sources:
- credential:
client-id: <CLIENT ID>
client-secret: <CLIENT SECRET>
endpoint: '<END POINT>'
profile:
tenant-id: <TENANT ID>
Here I have retriving the secret like this
#Value("${secret}")
private String secret;
and then I am just console logging them .
Output:
Keyvault:
