Keycloak 失败，因为它找不到我的主题或默认主题并出现 NullPointer 异常

Question

当我因另一个问题而不得不删除所有 docker 镜像时，我有一个可用的本地 keycloak 镜像。然后我再次调出我的钥匙斗篷图像

version: '3.6'\n\nvolumes:\n  keycloak_postgres_data: {}\n\nservices:\n  postgres-keycloak:\n      image: postgres:10-alpine\n      container_name: postgres\n      volumes:\n        - keycloak_postgres_data:/var/lib/postgresql/data\n      environment:\n        POSTGRES_DB: keycloak\n        POSTGRES_USER: keycloak\n        POSTGRES_PASSWORD: password\n\n  keycloak:\n      image: jboss/keycloak:4.1.0.Final\n      environment:\n        DB_VENDOR: POSTGRES\n        DB_ADDR: postgres\n        DB_DATABASE: keycloak\n        DB_USER: keycloak\n        DB_PASSWORD: password\n        KEYCLOAK_USER: admin\n        KEYCLOAK_PASSWORD: testing\n      ports:\n        - 8088:8080\n      volumes:\n        - ./themes/puretalent:/opt/jboss/keycloak/themes/puretalent\n        - ./themes/fifteenrock:/opt/jboss/keycloak/themes/fifteenrock\n      depends_on:\n        - postgres-keycloak\n\n

该卷中提到的主题存在于同一文件夹中，并且当我调出它时也在容器中。在领域设置中，我尝试将主题设置为我的特定主题或默认主题，但出现以下相同的错误。我\xe2\x80\x99ve将其省略到相关错误消息中。我还禁用了standalone.xml 中的缓存并重新启动了容器。

但是，我遇到了 NullPointer 异常。
