Webcontainer back to start terminates app

[nc-technologie]

Hello,

i have a problem, i use a webcontainer as background. To navigate back in the site i am using $back. It is all ok until i go back up to the starting page (URL String) . Then the app starts to loop and terminate if i click anything.

Thats the code:

// file://start.json

{
"$jason": {
"head": {
"title": "SFVM",
"actions": {
"$foreground": {
"type": "$reload"
},
"$load": {
"type": "$set",
"options": {
"url": [{
"{{#if $params && 'url' in $params && String($params.url).includes('google.com')}}": "{{$params.url}}"
}, {
"{{#elseif $params && 'url' in $params}}": "{{$params.url}}"
}, {
"{{#else}}": "https://www.google.com/"
}]
},
"success": {
"type": "$render"
}
},
"navigate": {
"type": "$href",
"options": {
"url": "file://start.json",
"options": {
"url": "{{$jason.url}}"
}
}
}
},
"templates": {
"body": {
"header": {
"title": "{{$get.url}}"
},
"background": {
"type": "html",
"url": "{{$get.url}}",
"style": {
"background": "#ffffff",
"progress": "rgba(0,0,0,0)"
}
"action": {
"trigger": "navigate"
}
},
"footer": {
"tabs": {
"style": {
"background": "#ffffff",
"color:disabled": "#cecece",
"color": "#cecece"
},
"items": [
{
"image": "file://back.png",
"text": "Zurück",
"action": {
"type": "$back"
}
},
{
"image": "file://search-interface-symbol.png",
"text": "Suche",
"action": {
"type": "$href",
"options": {
"url": "file://start.json",
"options": {
"url": "https://www.google.com"
}
}
}

                        },
                        {
                            "image": "file://user.png",
                            "text": "Konto",
                            "action": {
                                "type": "$href",
                                "options": {
                                    "url": "file://start.json",
                                    "options": {
                                        "url": "https://google.com"
                                    }
                                }
                            }
                        }
                        ]
                        
                    }
                }
                
            }
        }
    }
}

}

I hope anyone can help my with that.
