DAM OOTB Renditions not created.

Hi,

We are  uploading assets to DAM using JCROM API. We also have one custom workflow in AEM (6.1) which runs after a delay of 5 sec from the time of asset upload. Sometimes (not always) after image upload DAM OOTB asset workflow doesn't create renditions and it throws below error.

Hi,

Actually custom workflow isn't causing any issue. I just went to the line of code  in com.day.cq.dam.core.impl.cache.CQBufferedImageCache which was throwing null pointer .It was all about fetching properties of the asset.

As i was creating image nodes using jcrom api, tags property ( empty string []) was getting added which was causing the issue.

If tags property is there,we also need to have cq:taggable mixin else it throws this error.

Thanks,

Deepikaa

Good catch (as always). Might be within that time all the resources are not getting available. 

@Deepikaa, Please try what Loki has mentioned.

 

Thanks

what is the custom workflow you are running in 5sec delay ?

can you make it to 1min delay and see if you face this issue ?

Hi Deepikaa,

Since you are using custom workflow, could you set a debug point in your workflow and see from where the null pointer exception is coming. It looks like the workflow is triggered but because of some problem a null pointer exception is thrown. 

Debug > Indentify > handle the exception.

Please let us know if you are able to point out the issue after debugging.

Thanks
