Solved: Unable to create revision while metadata of asset ... - Adobe Experience League Community

View profile · 29-01-2019

Hi,

I have uploaded asset programatically by assetManager api and I am trying to set metadata properties for that asset. While doing this, i get following exception due to which few out of the box properties are not getting updated for the asset(ex. jcr:lastModified).

I tried checking damAssetState property , if its 'processed' i will be doing further actions on asset.

Resource assetData = resourceResolver.getResource(damPath + "/jcr:content");

while(someTimer){

String assetState = (String) assetData.getValueMap().getOrDefault("dam:assetState", "");

if (assetState.equalsIgnoreCase("processed")) {

// break loop and do next actions

}

Still i get same error and version doesnt get created. I feel 'dam-xmp-writeback' tries to send changes to renditions as soon as metadata node is modified. I do not have concrete solution yet. could you please let me know if you have nay thoughts on this?
