微信小程序订阅消息，thing.DATA不允许传空值吗？

{

    "data":{

        "thing3":{

            "value":""

        },

        "template_id":{

            "value":"f0cf5evoHrKbmBJu8Qdjljl3UKoYKG5jkr50GXoy59k"

        },

        "miniprogram_state":{

            "value":"trial"

        },

        "page":{

            "value":"sub-packages/mall-activity/pages/design/index?type=mallActivityOrderDetail&id=108020"

        },

        "lang":{

            "value":"zh_CN"

        },

        "thing1":{

            "value":"【测试0413】活动要审核"

        },

        "phrase2":{

            "value":"审核通过"

        }

    },

    "lang":"zh_CN",
