给小程序广告接入在数据回传

curl -k "https://api.weixin.qq.com/marketing/user_actions/add?version=v1.0&access_token=<ACCESS_TOKEN>" 
-d  '{ 
	"user_action_set_id": "<USER_ACTION_SET_ID>",
	"actions":[
		{
		    "url":"http://www.qq.com/pages/index/index",
		    "action_time":1647881574,
		    "action_type":"COMPLETE_ORDER",
		    "trace":{
			"click_id":"wx0ewinbalytptma00"
			},
		    "action_param":{
			"value": 10
		    }
		}
		]
	}' 
-H "Content-Type:application/json"

返回信息
{
	"errcode": 900351002,
	"errmsg": "payloads: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 1 column 13 path $.actions"

请问是什么原因呢？
