2304	error_page not applied vs Transfer-Encoding: chunked	ilsixela@…		"I've configured an error page in Nginx:

{{{
error_page 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414 415 416 417 418 421 422 423 424 425 426 428 429 431 451 495 496 497 500 501 502 503 504 505 506 507 508 510 511 /error.html;
location = /error.html {
  ssi on;
  internal;
  auth_basic off;
  root /etc/nginx;
}
}}}

This works fine for a 404. However I'm submitting a request like this:

{{{
POST /graphql HTTP/1.1
Content-Length: 2
Transfer-Encoding: chunked
Connection: close

{}
}}}

Note Transfer-Encoding: chunked. Nginx returns a 400 Bad Request error page of its own instead of mine. One minor clue is that the footer only says ""nginx"", it doesn't include a version. I tried adding ""server_tokens off;"" and it didn't change anything.

How do I make Nginx use my error page for ALL errors, please?"	defect	closed	minor		nginx-core	1.19.x	invalid	error_page	ilsixela@…	Linux gateway-79fdb46457-69njm 5.4.0-91-generic #102-Ubuntu SMP Fri Nov 5 16:31:28 UTC 2021 x86_64 Linux	"nginx version: nginx/1.21.5
