New Netlify runtime breaks Next.js

A few days ago, I’ve added one note and discovered that content pages on my site are not available anymore.

After a local testing I understood that locally everything is fine and there is something with Netlify infrastructure.

It seems that Netlify Next.js runtime v5 breaks pre Next 13.5 sites.

How to fix

1. Create netlify.toml file at the root of the project with following content:

[[plugins]]
  package = "@netlify/plugin-nextjs"

2. Install Netlify’s Next.js runtime v4: npm i @netlify/plugin-nextjs@4

After these steps, Next.js should work as intended.

P.S. Netlify probably notified users about their new runtime, but I somehow missed this.
