如果我在 Esri-React-Boot 上修改底图，则没有地图显示

问题描述

我被困住了，不知道我做错了什么。我目前只是想从 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，就像此处显示的教程（{{3} })，我没有得到任何地图渲染。

本教程使用 API 密钥，但在使用 OAuth 时，您不需要执行此类操作。

以下是我修改过的仅有的 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","@esri/arcgis-rest-portal": "^3.0.0","@esri/arcgis-rest-request": "^3.0.0","calcite-react": "^0.44.0","esri-loader": "^2.16.0","framer-motion": "^1.6.18","js-cookie": "^2.2.1","react": "^16.12.0","react-dom": "^16.12.0","react-redux": "^7.1.3","react-router-dom": "^5.1.2","react-transition-group": "^4.3.0","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。

这显示了底图的可用性，具体取决于是否使用 API 密钥。
