404 page not found when query params ends with file extension

[adriaandotcom]

If I go to my website on surge to this URL: https://example.com/login?email=test@test.com, I get this error:

If I go to these URLs it does work as expected (no 404):

• https://example.com/login?email=test@test.com&tralala
• https://example.com/?email=test@test.com
• https://example.com/login
• https://example.com/robots.txt
• https://example.com/robots.txt?file=robots.txt
• https://example.com/login?email=test@test

If I go to these URLs it does not work as expected (returns 404):

• https://example.com/login?email=test@test.com
• https://example.com/login?file=robots.txt

It looks like the path of the URL is being checked for a file extension, but also if it is a query parameter. It should only be checked when it is part of the filename.

I use a 200.html page to catch all the 404s which does not work, because I see the surge 404 page.
