Using Dispatcher code in AEM SPA cloud shortening the URL

[Ronnie09]

I have written Dispatcher rewrite to shorten the URL. Urls are being shortened but the page is not rendering anything it is appearing blank.

Model JSON is loading fine on both Publish and Dispatcher content is exactly the same. Screenshot is attached below

On Publish env

On Dispatcher

What shall I do now? I am confused

[Umesh_Thakur]

it seems you clientlibs are not loading, can you check is proxy enabled for the required clientlibs or not?

[Ronnie09]

@Umesh_Thakur 

Clientlibs are loading that icon is coming because of HTTP request. I tried to open in new tab it has the data

Can you check https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/aem-spa-react-dispatcher-s... for dispatcher setup with AEM SPA project.

Also, check AEM and dispatcher logs to see any error.

[Ronnie09]

Hi @rawvarun 

Yes, I check that solution out. My model json and the path are the same as well as there are no errors on the Dispatcher log.

For frontend changes,  I followed https://experiencing150.rssing.com/chan-25971229/article453.html

I don’t see .html file extension fir the dispatcher url. Can you check with .html extension for dispatcher url as well or you have setup on dispatcher to work as extension less url?

[Ronnie09]

@DPrakashRaj 

From dispatcher, I made extensionless URL

[DPrakashRaj]

So when you request page from dispatcher does the request going to aem publisher and if not then you might need to check the dispatcher rules for shortened url

How can I verify that?
My Dispatcher code

<IfModule mod_rewrite.c>

RewriteEngine on

    # rewrite for load root page

    RewriteCond %{HTTP_HOST} !^localhost    

    RewriteRule ^/?$ http://%{ENV:SAMPLE_HOST_PREFIX}%{HTTP_HOST}/us/en/home.html [R=301,L]

Check request.log and access.log of aem publisher

[Ronnie09]

@DPrakashRaj 

Request and access log are empty of publish, whenever I request 4503 then only it is printing someting. On hitting dispatcher url no log is printed on request.log and access.log

[DPrakashRaj]

That means your dispatcher is not configured correctly. You need to debug on the dispatcher by setting the dispatcher log as debug and check what happens with the request 

[purnatummalapalli]

Is the request going as full path to publisher from dispatcher after you rewrite in dispatcher?. It seems publisher could not process shorten url. We can enable shorten url using JcrResourceResolverFactoryImpl. Please check the below article.

How can I verify that request is going to publish. Currently, I just have a dispatcher which is handling everything.

we are also facing similar issue. Was there any solution for this?
