I have a situation where i need to make an AEM author post call from my OSGI Service, now we need some authentication to make this call , i tried with basic auth and it works absolutely fine. But i am looking for more secure option like by using bearer token and upon researching i found out we can use OAuth since JWT is deprecated. But after setting up OAuth i am getting 403 Forbidden from my api call response, earlier i used to get 401 unauthorized. Can someone suggest what should be the ideal setup for making AEM API calls using OAuth, it seems i have set it up incorrectly.

We are on AEMaaCS, we are working on introducing msm in our experience fragment hierarchy, we have created an xf in language masters in /content/experience-fragments/myProject/language-masters/en/header, now as it happens in site pages when we roll out a page from language masters , it automatically creates a live copy in /content/myProject/en/en_US, but in case of xf we have to manually create a live copy using create button, is there a way to automate this like it is there in sites pages.

How to make otblock.js from one trust load before a clientlib based on a specific condition ?

We are in process of migrating to new RHEL servers for our AEM Author on Dev.We had SAML configured on the Dev Author server which used load balancer url to login. The ACS url is also configured on this F5 url. This setup works fine.Now, we have diverted the traffic from this F5 to the new Dev Author, copied all the SAML configs as-is. Added +/Sites.html in Sling Authentication. However, when we attempt to login, it takes us to SSO, after successful login, it does not redirect to /sites.html and stays on the ping federate page.   

AEM as a Cloud Service is being used with ContextHub for personalization. After compilation, 32 JavaScript files(These files are already exists in code) are bundled into contexthub.kernel.js.A requirement exists to create a custom default segment that differs from AEM’s OOTB DEFAULT segment.The custom default segment was created using the following JavaScript:JavaScript(function () {    'use strict';    var MyDefaultSegment = function () {        return true;    };    /* register function */    ContextHub.SegmentEngine.ScriptManager.register(        'Region-Default',        MyDefaultSegment    );})();Show more linesScoring configuration:All region-specific segments (for example, Region-AA) are assigned a boost of 500Region-Default is assigned a boost of 2 (minimum boost)This works as expected when content is authored for all regions on the page.The issue occurs when a region-specific segment (for example, Region-AA) is resolved but no content is authored for that segment.

Has anyone else had any issue with their Condition Presets resetting back to nothing selected in the preset? Sometimes it happens in the source language and sometimes in one of the target languages, but not the others?When it happens in the source language, it had existed and the settings were saved, then a few months later it is zeroed out.

Hi,We have used Asset Insights to obtain basic asset measurements. Is there a way to combine these measurements in a more expanded way using Adobe Analytics, CJA, and Workfront?Also, is there a way to integrate data from all four sources—Asset Insights, Adobe Analytics, CJA, and Workfront?Thanks.

When an image in DAM is moved from folder 1 to folder 2, we see that the content pages with references to the images are updated but the content fragments are not updated. Is there a way to make sure that anytime an image is moved, the references of the image in Content Fragments are also updated? I am using AEMaaCS. Thanks, David.

I’m having an odd issue when receiving translations back from our provider.  Issue:When translations are accepted back into AEM from our translation provider, I'm seeing a variance in the metadata the assets end up with in the target folder.  It's mainly one field: "cq:TranslationSourcePath" (needed for my purposes) Project 1: Results show the cq:translationSourcePath (along with other metadata) on the target (de_de) assets “jcr:content” node. Project 2: missing translation metadata, Note it’s a different project, same target (de_de) note one of the only fields that gets copied to the target asset.Please Note: I'm not convinced this is a translation provider-related issue, as the data already exists in the "staging" area that AEM creates when initiating translations. Please see the screenshot below for the temporary location created for the translation (this is before the translation was sent back to AEM, i.e., before it was deleted as part of clean up):  Conclusion:Because the data ex

The LTS Analyzer identified a handful of references to obsolete components in our custom code, which we remediated and were removed from the report on a subsequent run.What remains are many paths to out-of-the-box components that we have never used or referenced.  In our dev system, I used the Content Transformer to remove ALL paths (/content, /etc, /libs, /var) on both author AND PUBLISH instances, PRIOR to upgrade (6.5 SP21).After upgrade, everything is working fine.  Zero issues.  But now I am seeing conflicting information that the tool should not be used that way, specifically:Only /content and /etc paths should be removed by the Content Transformer. The Analyzer should only be run on author instances.  On publish instances you should remove the obsolete paths manually or some other method (not sure what that would be). And just to confirm, the Content Transformer must be run on a 6.5 classic instance, prior to upgrade.  It errors out on a upgraded LTS instance.  The error logs in

Does anyone know if there is a way to link AEM Assets Collection with Adobe Express Library?  

Hello CommunityWe are setting up the environment to enable SDI so that the content won't be cached for dynamic components. The only issue is, the CDN is caching the "nocache.html" files which ultimately caused the issues. If we verify using dispatcher URL, we see the expected changes. Currently we have configured Sling Dynamic Include OSGI config with ESI and followed the header rules as per this - https://experienceleague.adobe.com/en/docs/experience-manager-learn/cloud-service/caching/how-to/disable-caching?lang=enSetting nocache.html path with Header unset Cache-ControlHeader unset Surrogate-ControlHeader always set Cache-Control "no-store, max-age=0"Header always set Surrogate-Control "no-store, max-age=0" and Parent paths with some non zero TTLs along with these -Header set x-aem-esi "on"Header set x-aem-compress "on"But CDN is still caching the fragments with nocache selector.Do we need to configure cdn.yml file for this?

I am creating an excel file programmatically which stores some user info but this excel is created in publish env, is there any way such that i can bring this to author? I checked ReplicationManager API but its deprecated for reverse replication in AEM as cloud

Can we add multiple values for the path here. Is that possible in any AEM config. If yes how, and if not what are the other ways we can handle this. 

In Universal Editor, when trying to align text in Rich Text field by using default alignment option (left, center, right), it only adds inline style. Upon saving changes and exiting out of RTE, all inline styles are removed.I want to have per-paragraph alignment option within a rich text field so didn’t do this through custom model field. Any fix for this? Like adding a class instead of inline styling so this can actually work?

We are using Adobe Experience Manager as a Cloud Service and need to share our Preview environment with a limited number of external users (outside our organization)for review before publishing to live dispatcher.Our production website is completely public (no authentication) and is protected by Imperva WAF on the live domain.For the Preview environment, our requirements are:Provide access only to a specific set of pages Prevent access to all other pages Ensure the environment is secure for external usersSince Preview behaves similarly to Publish and does not support fine-grained user/group permissions like Author, we are exploring the best approach.Our questions:What is the recommended way to restrict access to only specific pages in Preview? Should this be primarily handled at Dispatcher level, WAF (Imperva), or a combination of both? Are there any best practices for exposing Preview securely to external users in AEMaaCS?If anyone has implemented a similar setup, especially with Impe
