Cannot set properties of undefined (setting 'intl')

[WodenWang820118]

I was trying to integrate my tests into the Cypress dashboard. I had to get around the language detection overlay that I used the code:

import { defineConfig } from "cypress";

export default defineConfig({
  e2e: {
    setupNodeEvents(on, config) {
      on('before:browser:launch', (browser, launchOptions) => {
        if (browser.family === 'chromium') {
          launchOptions.preferences.default.intl = { accept_languages: 'zh-TW', selected_languages: 'zh-TW' }
          return launchOptions;
        }
      })
    },
  }
});

However, when I tried to run tests in the headless mode, it failed. The error message said:

Cannot set properties of undefined (setting 'intl')

Is there any way I can tackle this problem?

I just realized that after version 10, the npx cypress run command is removed, but I haven't seen it updated in the documentation. The workaround is using npx cypress run --browser chrome to run all my tests headlessly. To upload the testing results with --record, use npx cypress run --browser chrome --record <recordKey>
