Warning: StackView: cannot transition an item that is anchored! Why?

Hello!
I've got this warning in logs:

StackView: cannot transition an item that is anchored!

I've never been having this kind of troubles before. Is there any manuals to read about it? I mean about this waring. For me isn't clear right now about which items shouldn't be anchored.

import QtQuick 2.15
import QtQuick.Controls 1.4

SScreenContentTemplate {

	id: oRoot;
	color: oApplicationWindow.pColorBackground;

	StackView {

		id: oStackView;
		width: parent.width;
		height: parent.height;
		anchors.top: parent.top;
		anchors.bottom: parent.bottom;
		anchors.left: parent.left;
		anchors.right: parent.right;

		Component.onCompleted: {

			oStackView.push(oScreenLogin);
		}

		Component {id: oScreenLogin; SScreenLogin {}}
		Component {id: oScreenSearch; SScreenSearch {}}
		Component {id: oScreenRegister; SScreenRegister {}}
		Component {id: oScreenMainMenu; SScreenMainMenu {}}
		Component {id: oScreenTest; SScreenTest {}}

		delegate: StackViewDelegate {

			function transitionFinished(inProperties) {

				inProperties.exitItem.opacity = 1;
			}

			pushTransition: StackViewTransition {

				PropertyAnimation {

					target: enterItem;
					property: "opacity";
					from: 0;
					to: 1;
				}

				PropertyAnimation {

					target: exitItem;
					property: "opacity";
					from: 1;
					to: 0;
				}
			}
		}
	}

	function onSgOrientationChanged(inOrientation) {}
}

Which anchors should be dleted?

Solution found. Issue closed.
In one of Components - SScreenSearch was this line:

anchors.fill: parent;
