GitHub Actions 似乎无法识别我的 .env 机密

问：

我有一个 Playwright 项目，我正在尝试使用文件和 GitHub 机密进行身份验证。.env

我：.env

USERNAME={redacted}
PASSWORD={redacted}

在测试本身（在本地通过）中，我使用了 TypeScript 的语法：process.env.{variable}!

test.describe.serial('Dashboard', () => {
  test.beforeEach(async ({ page }) => {
    await page.goto('/');
    await page.getByPlaceholder('Email').fill(process.env.USERNAME!);
    await page.getByPlaceholder('Password').fill(process.env.PASSWORD!);

在 GitHub 中，我设置了与存储库机密相同的变量。这是我的文件：playwright.yml

name: Playwright Tests
on:
  push:
    branches: [ main, master ]
  pull_request:
    branches: [ main, master ]
jobs:
  test:
    timeout-minutes: 60
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - uses: actions/setup-node@v3
      with:
        node-version: 18
    - name: Install dependencies
      run: npm ci
    - name: Install Playwright Browsers
      run: npx playwright install --with-deps
    - name: Run Playwright tests
      run: npx playwright test
      env:
        USERNAME: ${{ secrets.USERNAME }}
        PASSWORD: ${{ secrets.PASSWORD }}
    - uses: actions/upload-artifact@v3
      if: always()
      with:
        name: playwright-report
        path: playwright-report/
        retention-days: 30

当测试在 GH 中运行时，似乎正在正确访问机密，但是当测试到达第一个断言时，测试将不可避免地失败：

Run npx playwright test
  npx playwright test
  shell: /usr/bin/bash -e {0}
  env:
    USERNAME: ***
    PASSWORD: ***

...
**.spec.ts:16:7 › *** › create a new *** ────

    Test timeout of 30000ms exceeded while running "beforeEach" hook.

      3 |
      4 | test.describe.serial('Stress testing UI', () => {  
    > 5 |   test.beforeEach(async ({ page }) => {
        |        ^
      6 |     await page.goto('/');
      7 |     await page.getByPlaceholder('Email').fill(process.env.USERNAME!);
      8 |     await page.getByPlaceholder('Password').fill(process.env.PASSWORD!);

        at /home/runner/work/{redacted}/{redacted}/tests/***.spec.ts:5:8

    Error: locator.click: Page closed
    =========================== logs ===========================
    waiting for getByRole('link', { name: '{redacted}' })
    ============================================================

       8 |     await page.getByPlaceholder('Password').fill(process.env.PASSWORD!);
       9 |     await page.getByRole('button', { name: 'Sign in' }).click();
    > 10 |     await page.getByRole('link', { name: '{redacted}' }).click();

我做错了什么？

我做了什么，我的期望是什么： 我编写的 Playwright 测试在本地通过，但在 GH 中运行时失败。GH 机密似乎正在以 UNDEFINED 或类似方式传递。

我希望我的应用程序在云中成功进行身份验证，就像在本地进行身份验证一样。
