"Invariant failed" error and a blank page
I have a simple app with two ssr pages and whenever I'm making a production deployment, for around a minute part of the requests to the server are not returning the website but rather this error in browser console and an empty page:
No logs on the server itself. After a that minute or so, all requests work normally.
