nginx redirects with changed response code

Question

I am trying to redirect any location that gives 404 to the front page and change the response code to 302.

According to nginx documentation this should be possible?

https://nginx.org/en/docs/http/ngx_http_core_module.html#error_page

But I keep getting 404 with the old 404 page. Caches are cleaned, cloudflare is in development mode and purged.

What am I doing wrong?

server {
   ...
   error_page 404 =302 https://example.com/home/;
   ...

Answer 1

Two things to try :

(1) Change
error_page 404 =302 https://example.com/home/;
to
error_page 404 =302 /home/;
[ I might suggest that you should also test without changing the response code ]

(2) Put that in a location Context ( not within the Server Context ) & then test with that location level.
It will ensure that your Current location Context is over-riding that.
