The Gallery app is built with --no-packager flag but later the accessibility check tries to connect to localhost:8081, which is typically the Metro bundler port. This creates an inconsistency since the packager won't be running.

Suggested change
# Start Metro bundler (packager) in background
- script: |
echo "Starting Metro bundler..."
cd $(GalleryPath)
start "" cmd /c "npx react-native start"
timeout /t 10 /nobreak
displayName: 'Start Metro Bundler'

Why does it say Azure Pipelines failed to run 2 pipeline(s)?

Installing dependencies during the build process is inefficient and unreliable. These dependencies should be added to package.json and installed during the standard dependency installation step.

Suggested change
yarn add --dev accessibility-checker

The axe command is trying to test http://localhost:8081 but there's no evidence that a web server is started on this port. The Gallery app is launched as a native Windows executable, not a web server.

Suggested change
npx axe --chrome-options="--no-sandbox --disable-dev-shm-usage" --save accessibility-results.json --reporter json http://localhost:8081 || true
# Also run accessibility checks on any locally running RNW components
# The axe CLI cannot be used directly on the native Windows app, as it is not served on http://localhost:8081.
# To run accessibility checks, use Playwright or another tool to automate the native app UI.

This bash-style script with pipes and grep commands will fail on Windows agents. The pipeline should use PowerShell commands or cross-platform alternatives since this is targeting Windows build agents.

The pipeline expects JUnit XML files but the accessibility tools are configured to generate JSON files (accessibility-results.json). Either change the expected format to match the generated files or configure the tools to output XML format.
