Vercel ISR: page redirects to `page-isr` when using isr: true

I have the following route rule configured:

  routeRules: {
    '/schedule': {
      isr: 60 * 5,
    }
  },


✅ working

When navigating to /schedule from the client side (clicking a link), I can access the page.

On first hit, the page is generated, and on subsequent hits, Vercel serves from the cache.

🚨 not working

However, when navigating to the URL directly (typing in my browser), the server fails to load the page and redirects me /schedule-isr, which 404s.

Here are the headers I get from a curl call:
