如果我在 Esri-React-Boot 上修改底图，则没有地图显示

Question

我很困惑，不知道自己做错了什么。我目前正试图从 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，就像此处的教程所示（https://developers.arcgis.com/javascript/latest/display-a-map/), 我没有得到地图的任何渲染。

本教程使用 API 密钥，但在使用 OAuth 时，您不需要做那样的事情。

以下是我修改的仅有的 2 个文件，其他一切都与 repo 中的相同。

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",
    "styled-components": "^4.4.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "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"
    ]
  }
}

提前致谢。

这显示底图的可用性取决于是否使用 API 密钥。

如果我在 Esri-React-Boot 上修改底图，则没有地图显示
