错误原因

错误写法

wx.cloud.init({
  env: '我的云ID',
  traceUser: true
})

const db = wx.cloud.database()
const people = db.collection('people')

people.add({ // <- 报错
    'name': 'OnePerson',
    'score': 15
})

正确写法

wx.cloud.init({
  env: '我的云ID',
  traceUser: true
})

const db = wx.cloud.database()
const people = db.collection('people')

people.add({
	data: { // 必须加上data!
		'name': 'OnePerson',
		'score': 15
	}
})
