javascript - 响应转换器错误：未找到策略

Question

我有以下 gateway.config.yml 文件

http:
  port: 8080
admin:
  port: 9876
apiEndpoints:
  lags:
    path: '/lags/*'
serviceEndpoints:
  lags:
    url: 'http://lags:50001'
policies:
  - response-transformer
  - basic-auth
  - cors
  - expression
  - jwt
  - log
  - oauth2
  - proxy
  - rate-limit
  - verify-auth0-jwt
pipelines:
  lags:
    apiEndpoints:
      - lags
    policies:
      - log:
        - action:
            message: ${req.ip} ${req.method} ${req.originalUrl}
      - rate-limit:
        - action:
            max: 1
            windowMs: 1000
      - jwt:
        - action:
            secretOrPublicKeyFile: ./key/pubKey.pem
            checkCredentialExistence: false
      - response-transformer:
        - action:
            headers:
              add:
                content-type: "'application/json'"
      - verify-auth0-jwt:
        - action:
      - proxy:
        - action:
            serviceEndpoint: lags
            changeOrigin: true

当我运行它时，我得到了这个错误

api-gateway_1  | error: [EG:policy] Could not find policy response-transformer, Please make sure the plugins providing such policy
api-gateway_1  |        is correctly configured in system.config file.

它在 docker 容器中运行。我在 package.json 中定义了最新版本的 express-gateway。
