When user is not logged in, some redirects fail and the user gets the message:
"The website encountered an unexpected error. Please try again later."

The logs show:
"Error: Call to a member function getTimestamp() on null in Drupal\page_cache\StackMiddleware\PageCache->storeResponse() (line 262 of /public_html/core/modules/page_cache/src/StackMiddleware/PageCache.php) "

I'm wondering if this is related to this issue - https://www.drupal.org/node/2573807 - though the fact that that is still open after two years would tend to suggest that it's not considered critical.

Re-saving the redirect as a 307 seems to resolve the issue. I still get the problem with 301s.

For what it's worth, I've turned off page caching (not an ideal long-term solution) and that seems to fix it. But I'd love to see a fix too! Note that this only seems to be a problem on Drupal 8.4 sites; I have a Drupal 8.3.7 site where I can't replicate this problem.

Changing the redirect to a 307 got around it for me.

It's happening to me too. Since the migration to 8.4.0, I have the same 500 Error.

I'm getting the same error after upgrading to Drupal 8.4. I wasn't getting it on 8.3.4.

Same as DarkstarTom -- after upgrading to 8.4, we started seeing this on some pages with an active redirect. The latest patch on #2573807 fixed the issue for us -- patch applied with an offset of 25 lines.
