Symfony FOSElasticaBundle配置

我有个问题

• Symfony:4.4
• 弹性搜索：7.6.1
• FOSElasticaBundle:5.1
• PHP:7.2.26

我的配置：

fos_elastica:
    clients:
        default: { url: '%env(ELASTICSEARCH_URL)%' }
    indexes:
        app:
            finder: ~
            types:
                city:
                    properties:
                        name: ~
                    persistence:
                        driver: orm
                        model: App\Entity\City
                        provider: ~
                        finder: ~

php bin/console fos:elastica:populate

Root mapping definition has unsupported parameters:  [city : {dynamic_date_formats=[], _meta={model=App\Entity\City}, properties={name={type=text}}}] [reason: Failed to parse mapping [_doc]: Root map
  ping definition has unsupported parameters:  [city : {dynamic_date_formats=[], _meta={model=App\Entity\City}, properties={name={type=text}}}]]

命令：

fos_elastica:
    clients:
        default: { url: '%env(ELASTICSEARCH_URL)%' }
    indexes:
        app:
            finder: ~
            types:
                city:
                    properties:
                        name: ~
                    persistence:
                        driver: orm
                        model: App\Entity\City
                        provider: ~
                        finder: ~

php bin/console fos:elastica:populate

  ping definition has unsupported parameters:  [city : {dynamic_date_formats=[], _meta={model=App\Entity\City}, properties={name={type=text}}}]]

错误：

        default: { url: '%env(ELASTICSEARCH_URL)%' }
    indexes:
        app:
