react-scripts build：无法缩小此文件中的代码：opentok.js:1310

Question

I am getting a failed to minify the code error when building my react project using npm run build.

This is code that is causing the error. Can anyone suggest what I could do to fix this?

const createLogger = memoize(namespace => {
  /** @type Logger */
  const API = {};

  const setMethods = () => {
    Object.keys(logLevels).forEach(name => {
      const method = logLevels[name].method;
      const log = debug("OpenTok:" + namespace + ":" + name.toLowerCase());
      log.log = console[method].bind(console);
      API[name.toLowerCase()] = log;
    });
  };

  setMethods();
  return API;
});

My package.json

{
  "name": "react-basic-video-chat",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@opentok/client": "^2.17.0",

    "opentok-react": "^0.10.0",
    "react": "^16.13.1",
    "react-dom": "^16.13.1",

  }
}

My react-scripts package was out of date. Installing the latest version fixed my problem.
