[FIXED] How to convert a ByteString to String in yml file. GCP secret manager, spring boot

Issue

I followed the documentation https://docs.spring.io/spring-cloud-gcp/docs/current/reference/html/secretmanager.html#_secret_manager_property_source and the bootstrap.yml file looks like this:

spring:
   clouds:
     gcp:
       secret manager:
         enabled: true
         secret-name-prefix: "sm://"
         project-id: my-project-id
   data source:
     username: "${sm://datasource-username}"
     password: test

and the application.yml file looks like this:

spring:
   clouds:
     gcp:
       projectId: my-project-id
       SQL:
         instance-connection-name: "my-instance"
         databaseName: testDatabase

and I get this error:

Property: spring.datasource.username\n Value: ${sm://datasource-username}\n Origin: class path resource [bootstrap.yml] - 9:15\n

Reason: org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [com.google.protobuf.ByteString$LiteralByteString] to type [java.lang.String]\n\nAction:\n\nUpdate your application's configuration\n"}

I don't really understand what I'm doing wrong :( I think I need a converter(.toStringUtf8()) in bootstrap.yml, but I don't no how to implement a converter in yml file. Any idea is helpful, thanks a lot

Solution

I used this dependency and it worked:

implementation("com.google.cloud:spring-cloud-gcp-starter-secretmanager:3.2.1")
