消息模板如下：

发送内容如下：

{"touser":"omMLC4kud5CqZ5XK4xb3EvQPfHqY","data":{"date4":{"value":"2023-12-07 22:26"},"date3":{"value":"2023-12-07 11:21"},"thing5":{"value":"无"},"phrase1":{"value":"审核通过"}},"template_id":"dJY_jRPgRQ7AXsg_maIXtMwq4HESQUd9h5aOT_q5LgI","miniprogram_state":"formal","page":"/pages/user/campus/campus","lang":"zh_CN"}

通过Postman发送能够成功，然而spring boot 后端通过okhttp3发送时，返回

{"errcode":47001,"errmsg":"data format error rid: 6571d635-557bee7a-74508b6a"}

用rid获取日志如下：

{
    "errcode": 0,
    "errmsg": "ok",
    "request": {

        "request_body": "{\"touser\":\"omMLC4kud5CqZ5XK4xb3EvQPfHqY\",\"data\":{\"date4\":{\"value\":\"2023-12-07 22:26\"},\"date3\":{\"value\":\"2023-12-07 11:21\"},\"thing5\":{\"value\":\"无\"},\"phrase1\":{\"value\":\"审核通过\"}},\"template_id\":\"dJY_jRPgRQ7AXsg_maIXtMwq4HESQUd9h5aOT_q5LgI\",\"miniprogram_state\":\"formal\",\"page\":\"/pages/user/campus/campus\",\"lang\":\"zh_CN\"}",

        "client_ip": "117.129.90.37"
    }
}

我从日志看不出来格式有什么问题，请教一下问题在哪呢？
