[Bug] Week1: Airflow health check cell uses wrong API endpoint for installed version

Environment

• OS: macOS
• Docker Desktop: 28.1.1
• UV: 0.7.x
• Python: 3.12
• Airflow version: 2.10.3

Summary

The Week 1 notebook health check cell hits /api/v2/monitor/health, which is an Airflow 3.x endpoint. The container runs Airflow 2.10.3, which does not have this endpoint, causing a 404 and making students think Airflow is not working when it actually is.

Steps to Reproduce

1. Follow the Week 1 notebook setup
2. Run the Test Airflow Health cell:
   python复制

   response = requests.get("http://localhost:8080/api/v2/monitor/health", timeout=5)

3. Cell prints: ⚠ Airflow returned: 404

Root Cause

The notebook was written targeting Airflow 3.x, where the health endpoint is /api/v2/monitor/health. However the Docker image in compose.yml installs Airflow 2.10.3, which exposes its health endpoint at /health.

Confirmed via:

docker exec rag-airflow airflow version
# 2.10.3

curl http://localhost:8080/health
# {"metadatabase":{"status":"healthy"},"scheduler":{"status":"healthy",...},"triggerer":{"status":"healthy",...}}

Fix

Update the health check cell in week1_setup.ipynb to use the Airflow 2.x endpoint:

response = requests.get("http://localhost:8080/health", timeout=5)

Alternatively, if the intent is to use Airflow 3.x, update compose.yml to pin the Airflow image to a 3.x version and align the auth setup accordingly (also see bugtext-airflow1.md which is related).
