      }).catch(error => {
        console.log('',error)
        // handle error

    }
  },

// 云函数入口文件
const cloud = require('wx-server-sdk')

cloud.init({ env:"**************************"}) // 使用当前云环境

const db = wx.cloud.database()
// 云函数入口函数
exports.main = async (event, context) => {
  const wxContext = cloud.getWXContext()
  return await db.collection('product').add({
    data:{
      time:db.serverDate(),
      name:event.name,
      h_price:event.h_price,
      price:event.price,
      img:event.img,
      img_detail:event.img_detail,
      select_classify:event.select_classify,
      sale_volume:0
    }
  })

filePath应为字符串而不是对象，说明filePath 类型不对 ，你打印一下看看
