404 error when exceeding max values

[haihoale]

When I configuring the parameters such as
IMGPROXY_MAX_ANIMATION_FRAME_RESOLUTION , IMGPROXY_MAX_ANIMATION_FRAMES, IMGPROXY_MAX_SRC_FILE_SIZE, and IMGPROXY_MAX_SRC_RESOLUTION,

the server will respond with a 404 error if these limits are surpassed. Could you please provide guidance on setting up so that it returns the original image like ?skip=1 instead?

Would you mind sharing the edits you made or the minimum setup so I can reproduce the issue?

Nginx can be configured to fallback to the original image if imgproxy is unable to handle oversized images. This is done by capturing the HTTP 422 status code from imgproxy and switching back to the origin image.

The following setting needs to be modified to achieve this:

docker-imgproxy/nginx/nginx.conf

Lines 201 to 203 in b899059

	# fallback to error image and error HTTP status
	error_page 401 403 404 405 422 429 =404 @fallback;
	error_page 500 501 502 503 504 =503 @fallback;

Change it to:

# fallback to error image and error HTTP status
error_page 422 = @remote;
error_page 401 403 404 405 429 =404 @fallback;
error_page 500 501 502 503 504 =503 @fallback;

I hope it helps.

Thanks for support
I followed your instructions, but it didn't work. It only works if I add '?skip=1'
