reference pages showing empty from AEM assets while selecting any Asset and open references

Hi All,

We are seeing reference pages showing empty from AEM assets while selecting any Asset and open references rail from left top.

 

This image used one of the test page and able to see image in page as well.

 

As per validation, we are seeing below servlet call is returning empty results instead of showing results.

https://localhost:4502/mnt/overlay/dam/gui/content/assets/jcr:content/rails/references/items/referen...?item=%2Fcontent%2Fdam%2Fweb%2Femailtemplate%2Fheader-o-nepl.png&_=1700228984004

 

It could be great if some one share comments /suggestion's on this.

Requesting you to please check error.log, if you are noticing any errors or traversal queries, on accessing the references.

Hi Sikka

Thanks for the update, unfortunately there is no errors related to this call from error log.

@raju-komari I strongly feel you should see something in error logs, also can you post page screenshot on how image is used in page..

Hi Shashi,

Please find the screenshot below for JCR node structure and for this image ( this is the existing site ) references are showing, but when ever adding /replacing newly uploaded image into same place, not showing references.

Same issue for newly created pages with new images - not showing references and also logs not helping much to proceed further.

 

Existing site - Image showing references

After replacing with new image for above image

Hi @raju-komari ,

Can you see in browser console and check if you are getting error related to JS. Also let us know if you have customized any feature around it? A others suggested please do check the error log as well.


Thanks

Hi Tarun,

We are not seeing any JS error while selecting references where not showing references for newly added images , but existing ones showing references.

Attaching logs for opening image folder and selecting the image to show references.

Hi Sahni,

As i have mentioned in above reply, we are seeing issues with newly added images and also seeing issues with newly created pages where we are using existing images/new images .

I have shared logs and jcr node content structure as well, but there is no difference while updating new image into existing image.

 

I will ensure to share solution steps here once it is fixed, but it is not fixed yet and still analysis going on with different templates /pages/ new images etc ..

 

We are unable to proceed much due to this weird issue.

The potential factors contributing to this issue could be:

  1. Rendering Issues: The error log indicates an absence of a renderer for the "html" extension, potentially hindering the references page's rendering.

  2. Missing Resource: The log mentions an inaccessible resource, "/libs/dam/gui/content/assets/jcr:content/rails/references/items/references/items/list/items/copies/items/assetLanguageCopies/items/update/items/trigger/granite:rendercondition." This resource might be crucial for the references page to function correctly.

  3. Data Retrieval Issues: The error log suggests that the servlet call is returning empty results, implying that references are not being properly retrieved from the repository.

Troubleshooting Steps:

  1. JavaScript Error Check: Verify that no JavaScript errors are occurring on the page where the references should appear. JavaScript errors can sometimes disrupt page rendering.

  2. Resource Availability Verification: Ensure that the resource "/libs/dam/gui/content/assets/jcr:content/rails/references/items/references/items/list/items/copies/items/assetLanguageCopies/items/update/items/trigger/granite:rendercondition" exists and is accessible. If the resource is missing, it might need to be restored or reinstalled.

  3. Server Log Examination: Review the server logs for any additional errors or warnings related to the issue. The logs might provide further insights into the underlying cause.

  4. Template and Page Testing: Replicate the issue with different templates and pages to determine if it is specific to a particular configuration. This could help narrow down the problem's scope.

  5. Analyze the JCR node structure and compare it with the expected structure to identify any discrepancies.

Hi Sahni,

Sorry for the late reply.

We have tried to compare with jcr node structure validation with existing image which is showing reference and new image (updated one) ,  but not seeing any differences where all node properties looks good for newly updated image.

and also not seeing any Javascript errors and abnormal errors on this specific from error logs.

 

Even template level validation, we are seeing image references where pages are using on existing images , but not with new images - able to replicate same issue across all templates.

We are trying to do exercise with WS retail pages vs our website pages , keep you posted

 

Thanks

Hi @kautuk_sahni 

We tried with Service pack 6.5.17 alone where we have currently 6.5.16 SP and issue has been fixed.

But not getting exact cause with 6.5.16 if something wrong with customized content specific (templates/code etc) etc.

We are in process of upgrading SP with 6.5.19 with proper plan and keep you posted if any issues identified during SP upgrade.

 

Cheers

Raju
