在Esri-React-Boot上修改Basemap没有Map显示

Question

我被卡住了，不知道我做错了什么。我目前正在尝试从Esri (https://github.com/Esri/esri-react-boot)修改这个库。

它使用OAuth，但你可以查看地图而不必登录。但是，如果我想修改basemap配置以显示arcgis-topographic，就像这里的教程(https://developers.arcgis.com/javascript/latest/display-a-map/)一样，我没有得到任何地图的渲染。

本教程使用API Key，但当使用OAuth时，您不需要做任何类似的事情。

下面是我只修改过的2个文件，其他的都和在repo中一样。

json

{
"appVersion": "2.0.0",
"apiUrl": "api",
"loginUrl": "api/auth/arcgis",
"logoutUrl": "api/logout",
"jsapiUrl": "https://js.arcgis.com/4.17/",
"jsapiV4": true,
"clientId": "<hidden>",
"sessionId": "esri-react-boot_session",
"mapConfig": {
"basemap": "arcgis-topographic",
"center": [-118.805, 34.027],
"zoom": 13
}
}

package.json

{
"name": "react-jsapi-app",
"version": "0.1.0",
"private": true,

}

提前谢谢你。

https://developers.arcgis.com/javascript/latest/api-reference/esri-Map.html#basemap

这显示了基图的可用性，这取决于是否使用API Key。
