获取汇报列表，是反馈参数错误，查不出哪错了？

参数是：{“starttime”:1619049600,“endtime”:1621209600,“cursor”:0,“limit”:10,“filters”:[{“key”:“creator”,“value”:“****”},{“key”:“department”,“value”:“1”},{“key”:“template_id”,“value”:“*******”}]}

反馈是{“errcode”:301066,“errmsg”:“Warning: wrong json format. param error, hint: [1621301954_171_580d381887d42910efea59485aa97e68], from ip: 219.142.14.162, more info at https://open.work.weixin.qq.com/devtool/query?e=301066”,“journaluuid_list”:[]}

那位高手，看看哪错了
