[Appium 1.15] Can't locate elements in webview with id

Just updated to appium v1.15, and the locators that use ids in the webpage of our app throw 'Invalid argument: invalid locator" exceptions.

eg. findElement(By.id(id)) - throws invalid argument: invalid locator exception
findElement(By.xpath("//*[@id=id]")) - works just fine

Appium version : 1.15
Java libaries: using latest commit branch 53814cd5ac77cf26e73c89eee49649af39f9c5a5

Hey @mykola-mokhnach ,

This is exactly what I was looking for.

Can you maybe help me Enforce chromedriver to JSONWP mode (set w3c chromedriver option to false )?

I was unable to find any code snippet on how to do this in java. Is it possible?

I only found ‘MobileCapabilityType.FORCE_MJSONWP’ which does not work.

I also tried:

ChromeOptions co = new ChromeOptions();
co.setCapability(“w3c”,false);
co.setCapability(“androidPackage”,“com.android.chrome”);
desiredCapabilities.setCapability(AndroidMobileCapabilityType.CHROME_OPTIONS, co);

But when using like this, the server will not even start, it will fail with:

/usr/local/lib/node_modules/appium/build/lib/main.js: error: argument “-dc/–default-capabilities”: Invalid parseDefaultCaps

Even without setting any capabs in ChromeOptions, the server fails to start as soon as I pass the ChromeOptions object to the desiredcapabilities
