uiautomator2+java 无法识别微信小程序元素

问题描述：
用uiautomator2+java 一路自动操作微信没问题（setUp()中的代码正常运行），但是进入微信小程序就提示对象找不到（test1()中的这一行就报错）。我试了好几小程序结果都一样，进小程序找元素就报.NullPointerException

问题代码

package com.example.yxmtestcase;

import android.app.Instrumentation;

import androidx.test.InstrumentationRegistry;
import androidx.test.runner.AndroidJUnit4;
import androidx.test.uiautomator.By;
import androidx.test.uiautomator.UiDevice;
import androidx.test.uiautomator.UiObject2;
import androidx.test.uiautomator.Until;

import org.junit.After;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;

@RunWith(AndroidJUnit4.class)
public class UiAndroidDaoDao {
    public Instrumentation instrumentation;
    public UiDevice uiDevice;

    @Before
    public void setUp() throws Exception{
        //初始化场景
        instrumentation = InstrumentationRegistry.getInstrumentation();
        uiDevice = UiDevice.getInstance(instrumentation);
        //亮屏
//        uiDevice.wakeUp();
//        Thread.sleep(1000);
        //进微信
        uiDevice.findObject(By.text("微信")).click();
        Thread.sleep(1000);
        //点发现
        uiDevice.click(669,2138);
        Thread.sleep(1000);
        //点小程序
        uiDevice.findObject(By.text("小程序")).click();
        Thread.sleep(1000);
        //点我的小程序
        uiDevice.findObject(By.text("我的小程序")).click();
        Thread.sleep(1000);
        //点稻草人旅行
        uiDevice.findObject(By.text("CoCo都可手机点单")).click();
        Thread.sleep(3000);
    }

    @Test
    public void test1() throws Exception {
        uiDevice.findObject(By.text("预约免排队")).click();
        Thread.sleep(3000);
    }
    @After
    public void tearDown() throws Exception{
        //恢复场景
        //点击关闭
    }
}

运行结果及报错内容

我的解答思路和尝试过的方法

用xy坐标是可以点击到元素，但是我后期是要从页面拿数据的，xy显然不可行

我想要达到的结果

uiautomatorviewer 获取到的对象也是 text "预约免排队" 但是通过代码就是报错
