Add failing test for res.redirect

[afzalsayed96]

Hi,

I was trying to deploy a Next site with preview mode on Netlify and was stuck on this error for quite some time:

The final solution that resolved the issue was changing

  res.redirect(req.query.slug)

to

  res.writeHead(307, { Location: req.query.slug });
  res.end();

I'm under the impression that the first syntax is supposed to be valid and was taken from the official Next.js docs for preview mode. Hence, I've created a failing test so anyone here could take a look at the issue and find the root cause if interested.

Thanks and cheers!

If this is something that's already known then I apologise and would like to suggest that it be documented somewhere with higher visibility.

was just able to repro in my own project after deploying. not immediately clear why this is happening but will investigate and keep you updated. thanks for opening this with the test <3.

update: we think we've discovered the issue here. i think @FinnWoelm will be opening his own PR soon!
