想实现一个跳转页面功能

页面 index.ets

.onClick(()=>{
  router.pushUrl({
    url: 'pages/second',
    params:{
      src:'传过来的数据'
    }
  })
})

…

页面 second

Button('点我返回')
  .fontColor(Color.Gray)
  .width(50)
  .padding(25)
  .onClick(() =>{
    router.back()
  })

…

main_pages.json

{
  "src": [
    "pages/Index",
    "pages/second"
  ]
}

…

无法跳转，页面2一直报上面的错误，求各位朋友帮忙
