Rollout failing due to conflicting mixin (and using the ClassicUI)
Learn how to fix rollout fails due to conflicting mixin (using the ClassicUI) with content update action configuration.
Description description
The rollout of a page is failing due to some conflicting jcr:mixinTypes on the page’s thumbnail node.
The conflict occurs when the page was configured with a thumbnail using the ClassicUI and then initially rolled-out (first roll-out works).
At this point, doing a rollout of the master page is failing due to conflicting mixin on the page’s thumbnail structure, between:
- dam:Thumbnails
- cq:LiveRelationship
The given error in the log is as follow:

Steps to reproduce:
- start a vanilla AEM 6.5.13.0
- go to /siteadmin (so using ClassicUI)
- open the page properties of /content/we-retail/language-master/en/women
- in the image tab set any image as thumbnail
- rollout the page
- now go to Sites UI
- open the page properties for /content/we-retail/us/en/women again
- in the Thumbnail tab, click on Generate Preview and save the change
- now rollout again the page in /siteadmin
Resolution resolution
This issue occurs during rollout beacuse AEM is unable to create “dam:thumbnails” node below jcr:content for live copy page (https://experienceleague.adobe.com/content/we-retail/us/en/women/jcr:content/image/file/jcr:content?lang=en) and reason for that is during rollout mixinType “dam:Thumbnails” is not appplied to live copy page node “/content/we-retail/us/en/women/jcr:content/image/file/jcr:content” and “dam:Thumbnails” folder can be created only below “dam:Thumbnails” nodeType.
MSM Default behaviour is to ignore new mixin added to the nodes at source during rollout [ 0] and hence it does not gets added to “/content/we-retail/us/en/women/jcr:content/image/file/jcr:content”.
In order to fix this issue, This behaviour can be changed via content update action config.
Default every mixin Type is being ignored as shown in the screenshot below:
It should be updated to use:
(?!.*dam:Thumbnails).*
as shown in the screenshot below:
This should fix the problem.
