Cloudflare Workers Response "Just a Moment..."

That’s a Firewall Challenge. Your Firewall Event Logs should show why that request is being challenged. Security Events · Cloudflare Web Application Firewall (WAF) docs

I am not sure if Cloudflare allow to bypass such request , in ideal world you should be able to create a WAF bypass rule specifically for requests from Vercel :

  1. Go to Cloudflare Dashboard > Security > WAF > Custom Rules

  2. Create a new rule with:

  3. Name: “Vercel Bypass”

  4. Expression: (http.request.headers["X-API-Key"] eq "YOUR_SECRET_KEY")

  5. Action: “Bypass”

I will recommend reaching out to Cloudflare support team for specific guidance.
