'react-admin'アプリをデプロイすると、Herokuサーバーが「JavaScriptヒープメモリ不足」でクラッシュする

現在、ローカルでうまく機能する 'react-admin'を使用して管理パネルを開発していますが、Herokuにアプリをアップロードするとすぐに、次のエラーでビルドが失敗します。割り当てに失敗しました-JavaScriptヒープがメモリ不足です

「react-admin」パッケージと管理者の単純なインポートのみを使用してクリーンなプロジェクトを設定することで、問題を最初のimport { Admin } from 'react-admin';に絞り込みました。コンポーネントを使用しようとすると、「ヒープがメモリ不足です」というエラーが発生してデプロイが失敗します。

他の誰かがこの問題に遭遇しましたか？

これが私のpackage.jsonです：

{
  "name": "mrewards_admin",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "axios": "^0.19.0",
    "deepmerge": "^4.2.2",
    "prop-types": "^15.7.2",
    "react": "^16.12.0",
    "react-admin": "^3.0.2",
    "react-dom": "^16.12.0",
    "react-scripts": "3.2.0"
  },
  "engines": {
    "node": "13.0.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

そして、これがHerokuログ出力です：

この作業を行うことができた唯一の方法は、有料のdynoにアップグレードし、package.jsonのスクリプトを次のように変更することでした。

"scripts": {
    "start": "node --max_old_space_size=2048 node_modules/.bin/react-scripts start",
    "build": "node --max_old_space_size=2048 node_modules/.bin/react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }

スクリプトの変更が必要かどうかはわかりません。展開中にメモリ使用量が1Gbを超える
