运行uni-app自动化用例报错TypeError: el3.$ is not a function

测试用例如下:
describe('pages/default/launch/launch.vue', () => {
let page;
beforeAll(async () => {

  page = await program.reLaunch('/pages/default/launch/launch')  
  await page.waitFor(3000);  

});

it('check page title', async () => {
const el = await page.$('.table-text-container-text');
el.tap();
await page.waitFor(5000);
// 进入目的地页面

   const page1 = await program.currentPage();     
   const path1=page1.path  
   expect(path1).toEqual('pages/toolPage/page/city/city');       
   let el0=await page1.$('scroll-view');  
   console.log(111+await el0);  
   let el1=await el0.$('.city-input');  
   console.log(222+await el1);        
   el1.tap();  
   await el1.input("直连测试酒店（请勿购买）");  
   await  page1.waitFor(2000);  
   let el2=await el0.$('.search-list-mt45');  
   console.log(333+await el2);  
   await  page1.waitFor(2000);  
   el2.tap();  
   let  el3=el2.$('.search-list-item-box');  
   console.log(444+await el3);  
   let  el4=el3.$('.search-list-hotel-item');  
   console.log(555+await el4);  
   await  page1.waitFor(2000);  
   el4.tap();  

});
});
