Google Secret Manager: don't get value from it with Spring Boot - spring-boot

Question

I follow the instructions from this post: https://github.com/spring-cloud/spring-cloud-gcp/tree/master/spring-cloud-gcp-samples/spring-cloud-gcp-secretmanager-sample
After starting the application everything is working fine.
Then I implement it in my Spring Boot application and I get //application-secret and not the value for the secret.

bootstrap.properties
spring.cloud.gcp.secretmanager.bootstrap.enabled=true
my-app-secret-1=${sm://application-secret}
Controller:
#RestController
public class DefaultController {
#Value("${my-app-secret-1}")
private String secret;
#Value("${sm://application-secret}")
private String appSecret;
#GetMapping(value = "/")
public ResponseEntity<String> start() {
return ResponseEntity.ok("Worked");
}
#GetMapping(value = "/secret")
public ResponseEntity<String> getSecret(){
return ResponseEntity.ok(secret + " --- " + appSecret );
}
}
Any Idea what I can do?

The problem comes from your prefix. I don't see in your bootstrap.properties file the prefix mention. Add this in the file
spring.cloud.gcp.secretmanager.secret-name-prefix=sm://
It works for me
