AEM Dispatcher ErrorDocument URL not showing up

Hi AEM Community,

 

I have the below Error Document vhost configuration written for my site -

ErrorDocument 404 /content/xyz/us/en/errors/404.html

When I am hitting an incorrect URL my dispatcher logs show the below - 

172.17.0.1 "localhost" - [05/Aug/2022:07:16:25 +0000] "GET /content/xyz/us/en/abc.html HTTP/1.1" 301 233 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:103.0) Gecko/20100101 Firefox/103.0"
172.17.0.1 "localhost" - [05/Aug/2022:07:16:25 +0000] "GET /abc.html HTTP/1.1" 404 2425 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:103.0) Gecko/20100101 Firefox/103.0"
[05/Aug/2022:07:16:25 +0000] "GET /content/xyz/us/en/abc.html HTTP/1.1" 404 none [publishfarm/0] 13ms "localhost"

 

The above entries are due to the below redirect rules - 

RewriteRule ^/content/xyz/us/en/(.*)$ /$1 [NE,L,R=301]
RewriteRule ^/(.*)$ /content/xyz/us/en/$1 [NC,PT,L]

 

However, once the redirection occurs and 404 was encountered I was expecting the logs to redirect to error page as defined in ErrorDocument directive.

 

Can anyone please suggest what is wrong in this ?

Currently the request passes to publish and is served with the below -

    Hi, I tried in local with docker image it worked for me.
    Here are my changes in 

    1. created new vhost file at /dispatcher-sdk-2.0.104/src/conf.d/available_vhosts/aemlab.vhost, it is a copy of /dispatcher-sdk-2.0.104/src/conf.d/available_vhosts/default.vhost but added 

    <LocationMatch />
ErrorDocument 404 /content/aemlab/404.html
ErrorDocument 403 /content/aemlab/403.html
ErrorDocument 500 /content/aemlab/500.html
</LocationMatch>

    2. unlink /dispatcher-sdk-2.0.104src/conf.d/enabled_vhosts/default.vhost

    3. created symblink ln -s /dispatcher-sdk-2.0.104/src/conf.d/available_vhosts/aemlab.vhost /dispatcher-sdk-2.0.104/src/conf.d/enabled_vhosts/default.vhost

    4. executed below command

    ./bin/validator full -d ./out ./src

    Hi,

    Try changing this to below so that it matches your rules.

    ErrorDocument 404 /errors/404.html

      Hi @arunpatidar , Thanks for the quick reply.

        I think,

        This is not executing otherwise you could you please check dispatcher logs, try debug logs?

        ErrorDocument 404 /errors/404.html

          Hi @rohan_garg ,

          Can you Please try checking the DispatcherPassError is updated in vhost,

          It should be set to DispatcherPassError 404 in this case.

            @achennapragada  - Thanks for the response. 

            DispatcherUseProcessedURL On
            DispatcherPassError 1

            The DispatcherPassError is set to 1. As the documentation says the following -

            Dispatcher does not spool an error response to the client (where the status code is greater or equal than 400), but passes the status code to Apache, which e.g. allows an ErrorDocument directive to process such a status code.
