I love Next.js!

Beginner Hint 1: Overview of the Challenge
  • If you read the Dockerfile, you can see that secret.js is renamed to a random filename. So instead of /secret, you need to access /secret-{32 random characters}.
  • The rest of the code looks like a minimal Next.js setup.
Beginner Hint 2: How to Approach the Challenge
  • What kind of network requests are made when you access the main page?
  • Someone may have reported having trouble because a hidden page was discovered in the past. Try searching the internet.
