WebP rewrite rules from NGINX issue

It appears to be a problem with NGINX rewrite rules for WebP display.

From a user:

I got the following error when running nginx -t :

– invalid parameter “final” in /usr/local/nginx/conf/vhost/www.xxx.com.conf:127 –

Current recommended NGINX rules by us:

# BEGIN Imagify: rewrite rules for webp
location ~* ^(/.+)\.(jpg|jpeg|jpe|png|gif)$ {
	add_header Vary Accept;

	if ($http_accept ~* "webp"){
		set $imwebp A;
	}
	if (-f $request_filename.webp) {
		set $imwebp  "${imwebp}B";
	}
	if ($imwebp = AB) {
		rewrite ^(.*) $1.webp final;
	}
}
# END Imagify: rewrite rules for webp
