如果我在Esri-React-Boot上修改底图，则不会显示地图

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，但您无需登录即可查看地图。但是，如果我想修改basemap配置以显示arcgis-topographic，就像教程在这里显示的那样(https://developers.arcgis.com/javascript/latest/display-a-map/)，我得不到任何地图的渲染。

本教程使用了一个API键，但是在使用OAuth时，您应该不需要这样做。

下面是我唯一修改过的2个文件，其他的都和repo中的一样。

config.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,
  "homepage": "/",
  "dependencies": {
    "@esri/arcgis-rest-auth": "^3.0.0",

    "redux": "^4.0.4",
    "redux-saga": "^1.1.3",

  },
  "scripts": {

    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },
  "devDependencies": {
    "react-scripts": "^3.3.0"
  },
  "browserslist": {
    "development": [
      "last 2 chrome versions",
      "last 2 firefox versions",
      "last 2 edge versions"
    ],
    "production": [
      ">1%",
      "last 4 versions",
      "Firefox ESR",
      "not ie < 11"
    ]
  }
}

提前谢谢你。

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

这显示了底图的可用性，这取决于是否使用API密钥。
