Wdio problem screenshot element

I can’t take a screenshot from a element of the screen. Can someone help me?

Appium desktop version: 1.5.0 (I not using the last one, because I had another problem with this version).

Now my code:

    const wdio = require('webdriverio');


const opts = {
    port: 4723,
    desiredCapabilities: {
	  "platformName": "Android",
	  "platformVersion": "7.0",
	  "deviceName": "0023048519",
	  "automationName": "UiAutomator2",
	  "appPackage": "com.android.calculator2",
  	  "appActivity": "com.android.calculator2.Calculator",
	  "noReset": "true",
	  "full-reset": "false"
	
	}
};
 
const driver = wdio.remote(opts);

driver.init()	.click('//*[@resource-id="com.google.android.calculator:id/digit_2"]')		
		.elementIdScreenshot('//*[@resource-id="com.google.android.calculator:id/digit_2"]').saveScreenshot('./snapshot.png')
		.end();

When I run this code I have the follow log:

When a take the screenshot the next message is “No route found. Setting content type to ‘text/plain’”. The appium find the elements, but not save it.

I can take and save a screenshot from all screen, but I have this problem when I try to take it from a element.

I don’t know what I’m doing wrong, every time I post no one help me.
