Cause

The Electron app has initialized the browser with webPreferences.contextIsolation: false:

  let win = new BrowserWindow({
...
    webPreferences: {
...
        contextIsolation: false,
...
    }
  });

Solution

To resolve the error, remove this line that initializes the browser with webPreferences.contextIsolation: false:

  let win = new BrowserWindow({
...
    webPreferences: {
...
        // contextIsolation: false, <-- remove this
...
    }
  });
