Spring Cloud Config @Value throwing Не найден конвертер, способный конвертировать из типа [java .util.LinkedHashMap ] введите [java .lang.String]

Я успешно установил соединение со службой конфигурации Spring Cloud для чтения моих реквизитов в файле application.yml извне в репозитории конфигурации. Но когда он пытается прочитать значения, я получаю эту ошибку

Исключение:

Error creating bean with name 'securityConfig': Injection of autowired dependencies failed; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.util.LinkedHashMap<?, ?>] to type [java.lang.String]

Мой класс конфигурации и значение, которое я пытаюсь прочитать: 

public class SecurityConfig extends WebSecurityConfigurerAdapter implements WebMvcConfigurer {

    @Value("${qws.client-realm}")
    protected String clientRealm;

Application.yml, который является внешним: 

spring:
  main:
    allow-bean-definition-overriding: true

qws:
  client-role: qws-client
  client-user-name: svc-client
  client-realm: QWS_CLIENT_REALM

bootstrap .yml 

spring:
  cloud:
    config:
      uri: https://config-service.abcd.com
      fail-fast:  false
      username: abcd
      password: xyz
management:
  endpoints:
    web:
      exposure:
        include: '*'
  endpoint:
    health:
      show-details: always

Spring Boot - это зависимости и версии от родителей и облака. Нет проблем со сборкой.

ЖУРНАЛЫ, когда мое клиентское приложение запускается и пытается прочитать конфигурацию через config-service (внешне). Служба Config общается с config repo, который имеет файл application.yml извне. Посмотрите на ПЕРВЫЕ 3 ЛИНИИ ниже журналов 

2020-04-20 22:14:25.999 [,,] INFO  [main                               ] o.s.c.c.c.ConfigServicePropertySourceLocator                                - Fetching config from server at : https://config-service.abcd.com

Полное исключение, которое происходит после того, как выше регистрируется подключение из config-service:
