Publishing assets stuck on status “Later”
The asset was successfully published after changing the cq:tags property type to String Array.
Description description
Environment
Adobe Experience Manager (AEM)
Issue
Continuous failure occurs while publishing multiple assets in AEM, especially images. Often their images got stuck on a never-ending status “Later” while at other times, they were stuck on the state “Pending”, failing into “Not Published”.
When trying to “Quick Publish” an asset, the error.log displays the following:

Resolution resolution
As can be seen in the error.log, the issue is caused by "javax.jcr.ValueFormatException: cq:tags = <value> is single-valued"
The cq:tags property is actually a String Array, which is a multi-valued property. However, in this case, it was of type String which led to the error.
Upon changing the cq:tags property type to String Array, the asset was successfully published.
