TypeError: Cannot read property 'route' of undefined react

Hi guys,

I have an error during swipeback
TypeError: Cannot read property ‘route’ of undefined
at Framework7.handleTouchEnd (swipe-back.js:552)
My app.jsx is about:

  render() {
    return (
      <App params={this.state.f7params} >
        {/* Status bar overlay for fullscreen mode*/}

        {/* Your main view, should have "view-main" class */}
        <View main className="safe-areas" url="/" />


i call the page in this way:

              <Link href="/contact/" text="View All" className="right"></Link>

contact is a normal page:
export default class extends React.Component {
    constructor(props) {
        this.state = {
            items: [
                    phone: '091111111',
                    label: 'Police',
    render() {
        return (
            <Page className="contact-page">
                <Appbar noHairline>
                    <div className="left">
                        <Button small href="/menu/" className="display-flex" iconF7="bars" />
                    <div className="center">
                        <img src="/static/img/shared/logo-bar.svg" className="logo-appbar"></img>
                    <div className="right">
                        <span className="has-notification"></span>
                        <Button small href="/notifications/" className="display-flex" iconF7="bell" />
                <List className="main-list" noHairlines>
                    <ListItem className="section-thumb gallery">
                            <BlockTitle medium>Contact</BlockTitle>
                <Block className="items">
                    {this.state.items.map((item, i) => (
                            key={'row-' + i}
                            <Col width="75">
                            <Col width="25">
                                <Button href={'tel:' + item.phone} external text="Call" fill></Button>
                <Toolbar labels position='bottom' noHairline >
                    <Link href="/gallery/" tabLinkActive text="Photocontext" iconIos="f7:images"></Link>
                    <Link href="tel:1111" external text="Contact Us" iconIos="f7:phone_fill" ></Link>
                    <Link href="/faq/" text="Faq" iconIos="f7:tickets" className="last" ></Link>

Hard to say like that, the code looks correct. Would be good to see live example or minimal JS fiddle with the issue
