Config client não recupera as propriedades do server

Meu config client não consegue recuperar as informações do config server, ele loga que se conectou com o server, mas não consegue configurar o datasource:

2020-07-21 09:31:00.376  INFO 11220 --- [  restartedMain] c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at : http://localhost:8888
2020-07-21 09:31:01.834  INFO 11220 --- [  restartedMain] c.c.c.ConfigServicePropertySourceLocator : Located environment: name=configServer, profiles=[default], label=null, version=null, state=null
2020-07-21 09:31:01.842  INFO 11220 --- [  restartedMain] b.c.a.m.f.FornecedorApplication          : No active profile set, falling back to default profiles: default

***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class

As configurações no meu config server estão assim:

server:
  port: 8888

spring:
  profiles:
    active: native
  application:
    name: configServer
  cloud:
    config:
      server:
        native:
          search-locations: c:/Users/jorge_neto/Desktop/workspace/Alura/spring boot/micro-repo

As configurações no client estão assim:

spring:
  application:
    name: 'fornecedor'

  cloud:
    config:
      name: configServer
      enabled: true
      uri: http://localhost:8888

no diretório tenho um arquivo chamado fornecedor.yml, com essas configs:

spring:
  jpa:
    hibernate:
      ddl-auto: update

  datasource:
    url: jdbc:mysql://localhost:3306/fornecedor?useTimezone=true&serverTimezone=UTC
    username: root
    password: er45

no postman, o config server responde assim:

{
    "name": "fornecedor",
    "profiles": [
        "default"
    ],
    "label": null,
    "version": null,
    "state": null,
    "propertySources": [
        {
            "name": "file:c:/Users/jorge_neto/Desktop/workspace/Alura/spring boot/micro-repo/fornecedor.yml",
            "source": {
                "spring.jpa.hibernate.ddl-auto": "update",
                "spring.datasource.url": "jdbc:mysql://localhost:3306/fornecedor?useTimezone=true&serverTimezone=UTC",
                "spring.datasource.username": "root",
                "spring.datasource.password": "er45"
            }
        }
    ]
}
