qrc://scrollbar.qml:-1 No file name specified

[Slv007]

I have old project, now I tried to update it to Qt 5.8 and QtQuick.Controls 2.1, but I got error

qrc://scrollbar.qml:-1 No file name specified

this error is produced by code :

import QtQuick 2.7
import QtQuick.Controls 2.1
import QtQuick.Layouts 1.1

Flickable{
        id:flickable
        anchors.fill: parent
        ScrollBar.vertical: ScrollBar { }
    }

I'm running this code on Android phone. What is wrong here ?

Problem solved. I forgot that I have the ScrollBar.qml as custom scrollbar already. So, just renaming it solves the problem.

@Slv007 It may be a deployment problem. Have you created a new project and copied your code files from the old one or trying to use existing project files, .pro etc.?

I'm using existing project, just changed header of QML file and added Scrollbar
