但是我按照文档导入抽样数据出现如下问题能帮忙解答下么
https://api.weixin.qq.com/wxa/setdynamicdata?access_token=？ post如下官方文档数据后{ "data": "{\"items\":[{\"from\":{\"city_name_cn\":\"广州市\"},\"to\":{\"city_name_cn\":\"北京市\"}}], \"attribute\": {\"count\": 1, \"totalcount\": 100, \"id\": \"1\", \"seq\": 0}}", "lifespan": 86400, "query": "{\"type\":100005}", "scene": 1}
返回结果{ "errcode": 85057, "errmsg": "invalid widget data format", "search_widget_err_info": { "errcode": -2, "errmsg": "Fail catch unknown field \"from\", Error before \":{\"city_name_cn\":\"广州市\"},\"to\":{\"city_name_cn\":\"北京市\"}}], \"attribute\": {\"count\": 1, \"totalcount\": 100, \"id\": \"1\", \"seq\": 0}}" }}
