org.openqa.selenium.InvalidSelectorException: Unsupported CSS selector error when using #AndroidFindBy(uiAutomator = - scroll

Question

I am trying to automate a scenario in an android application using appium, java. I need to scroll down to an element on the screen to enter a text value. I'm initializing the elements using page factory as shown below.
#AndroidFindBy(uiAutomator = "new UiScrollable(new UiSelector().scrollable(true).instance(0)).scrollIntoView(new UiSelector().resourceId(\"com.call4site.handymanservices:id/email\"))")
private WebElement txt_email;
I'm getting a strange error in console as below.
org.openqa.selenium.InvalidSelectorException:
Unsupported CSS selector '*[name='txt_email']'. Reason: 'Error: 'name' is not a valid attribute. Supported attributes are 'checkable, checked, clickable, enabled, focusable, focused, long-clickable, scrollable, selected, index, instance, description, resource-id, text, class-name, package-name''

But if I use the following code to initialize the element, then I'm able to scroll down and enter text to it. Has anyone faced this issue?
WebElement txt_email = driver.findElement(AppiumBy.androidUIAutomator("new UiScrollable(new UiSelector().scrollable(true).instance(0)).scrollIntoView(new UiSelector().resourceId(\"com.call4site.handymanservices:id/email\"))"));
