我无法在本地Android应用（Appium，WebdriverIO，Mocha和Chai）上找到元素。
不确定为什么无法找到元素并将click()事件应用于该特定元素，以便它自动进入应用程序的下一个屏幕。而且不确定，这实际上意味着什么：
{"status":7,"value":"No element found"}
我也尝试这样做：
client.elementByXPath('xpath val')
但最后一行抛出：
elementByXPath not a function
我的代码：
describe('Testing', function(){
before(function(){
this.timeout(50000);
return client.init();
});
describe('Test CALCU addition', function(){
it('should display list of projects', function(){
client.click(
'android=new UiSelector().resourceId(
"uk.co.polestar.app:id/firstLineDisplayName")');
});
});
});
下面的错误日志：
