Symfony 5.4配置drenso/symfony-oidc-bundle遇错求助

我正尝试使用drenso/symfony-oidc-bundle配置OpenID连接，已完成bundle的基础配置，.env中对应变量也已设置，但在security.yml中启用oidc后出现错误（错误截图：），以下是我的配置内容，希望用过该包的开发者帮忙排查问题。

drenso_oidc配置 #

drenso_oidc:
    #default_client: default # The default client, will be aliased to OidcClientInterface
    clients:
        default: # The client name, each client will be aliased to its name (for example, $defaultOidcClient)
            # Required OIDC client configuration
            well_known_url: '%env(OIDC_WELL_KNOWN_URL)%'
            client_id: '%env(OIDC_CLIENT_ID)%'
            client_secret: '%env(OIDC_CLIENT_SECRET)%'

            # Extra configuration options
            #redirect_route: '/login_check'
            #custom_client_headers: []

        # Add any extra client
        #link: # Will be accessible using $linkOidcClient
            #well_known_url: '%env(LINK_WELL_KNOWN_URL)%'
            #client_id: '%env(LINK_CLIENT_ID)%'
            #client_secret: '%env(LINK_CLIENT_SECRET)%'

可能的排查方向 #

• 启用匿名访问：OIDC认证流程需要用户先以匿名身份访问跳转入口，取消front防火墙中#anonymous: ~的注释，开启匿名访问。
• 配置redirect_route：drenso_oidc默认回调路由是oidc_check，如果需要自定义路径，需确保redirect_route指向存在的有效路由，比如你注释的/login_check要对应正确的回调处理路由。
• 用户匹配逻辑：front_users提供者基于email字段查找用户，需确认OIDC返回的用户信息中包含匹配该字段的内容，或者配置自定义的用户加载器来适配OIDC响应数据。
• 版本兼容性：检查drenso/symfony-oidc-bundle版本与当前Symfony版本是否兼容，尤其是认证管理器（enable_authenticator_manager: true）的适配情况。
• 补充错误详情：若以上方向未解决问题，需提供截图中的具体错误文本，比如路由不存在、客户端配置无效或用户加载失败等信息。
