uniCloud：请求云函数：获取本地运行参数失败

1.云函数代码

'use strict';

exports.main = async (event, context) => {
	//event为客户端上传的参数
	console.log('event : ', event)
	console.log(context)
	
	  return {
	    event
	  }
};

2.前端调用代码

submitForm() {
				uniCloud.callFunction({
					name: 'login',
					data: this.formData
				}).then(res => {})
			}

3.错误提示：
