我开发第三方平台小程序的，在开发和测试过程一切都正常，上传代码和发布小程序成功后，打开下程序首页导航栏tabBar图标不见，ext.json里的ext字段里的属性也读取不了，这是怎么回事？求解答

ext.json 配置主要文件如下

{

"extEnable": true,

"extAppid": "wx0ba806b9XXXXXX",

"ext": {

"name": "微飞享",

"extAppid": "wx0ba806b9XXXXXXX"

},

"extPages": {

"pages/index/index":{

"navigationBarTitleText": "微XX"

},

"pages/logs/logs":{

"navigationBarTitleText": "日志"

},

}，

"window": {

"backgroundTextStyle": "light",

"navigationBarBackgroundColor": "#fff",

"navigationBarTitleText": "微XX",

"navigationBarTextStyle": "black"

},

"tabBar": {

"color": "#000",

"selectedColor": "#f40",

"list": [

{

"pagePath": "pages/index/index",

"text": "首页",

"iconPath": "./pages/image/icon/home1.png",

"selectedIconPath": "./pages/image/icon/home2.png"

},

{

"pagePath": "pages/find/find",

"text": "发现",

"iconPath": "./pages/image/icon/find1.png",

"selectedIconPath": "./pages/image/icon/find2.png"

},

{

"pagePath": "pages/cart/cart",

"text": "购物车",

"iconPath": "pages/image/icon/cart1.png",

"selectedIconPath": "./pages/image/icon/cart2.png"

},

{

"pagePath": "pages/my/my",

"text": "我的",

"iconPath": "./pages/image/icon/my1.png",

"selectedIconPath": "./pages/image/icon/my2.png"

}

]

},

"networkTimeout": {

"request": 10000,

"downloadFile": 10000

}

}

app.json 主要配置如下

"tabBar": {

"color": "#000",

"selectedColor": "#f40",

"list": [

{

"pagePath": "pages/index/index",

"text": "首页",

"iconPath": "./pages/image/icon/home1.png",

"selectedIconPath": "./pages/image/icon/home2.png"

},

{

"pagePath": "pages/find/find",

"text": "发现",

"iconPath": "./pages/image/icon/find1.png",

"selectedIconPath": "./pages/image/icon/find2.png"

},

{

"pagePath": "pages/cart/cart",

"text": "购物车",

"iconPath": "pages/image/icon/cart1.png",

"selectedIconPath": "./pages/image/icon/cart2.png"

},

{

"pagePath": "pages/my/my",

"text": "我的",

"iconPath": "./pages/image/icon/my1.png",

"selectedIconPath": "./pages/image/icon/my2.png"

}

]

},

在开发测试过程中，这些TabBar 图标配置是出来，ext.json 的 ext 字段也是正常获取的，上传代码，发布后之后，图标就不显示了
