DAM Update Asset Workflow not working

[chanakya]

Hi all,

I have just started working on AEM Assets. I am currently trying to upload an image asset from my local disk to my local AEM instance. I am providing those images some metadata properties such as dc:title and dc:description using Photoshop. However, these properties are not visible to me once I upload the asset to AEM. Also the vice-versa process from AEM to photoshop doesn't seem to work. Also renditions and thumbnails are not being generated for my asset once I upload those to AEM and the dam:assetState is always stuck at "unProcessed" everytime I upload any asset to AEM. I have never made any changes to my DAM Update asset workflow as I have just recently started working with assets and workflows. Please help me with this.

Thank you.

Hi @chanakya, could you please share following details:

• AEM version that you are using,
• what type (jpg, png etc) of asset you are trying to upload, if that is not a problem could you please share the problematic asset as well
• could you please check error.log and share the output related to workflow

Hi @lukasz-m ,

• My AEM version is 6.5.10.0
• I have tried to upload various and different kinds of images(png,jpg) but everything leads to the same issue.
• This is something I just encountered after checking the error logs: *WARN* [sling-oak-observation-3] org.apache.sling.event.impl.jobs.queues.QueueJobCache Unable to read job from /var/eventing/jobs/assigned/88cfbf79-98a9-4c05-a8b0-e67a678e40d7/com.adobe.granite.workflow.transient.job.var.workflow.models.dam.update_asset/2022/1/10/18/27/88cfbf79-98a9-4c05-a8b0-e67a678e40d7_10

Could you please try following steps:

1. Terminate all DAM workflow instance, you can do this from:
   1. /libs/cq/workflow/content/console.html or
   2. /libs/cq/workflow/admin/console/content/instances.html
2. Open crx/de, navigate to /var/eventing/jobs/assigned and find com.adobe.granite.workflow.transient.job.var.workflow.models.dam.update_asset folder and remove it with all child nodes.
3. Restart AEM.

Hi @lukasz-m ,

Thanks for the response, tried the above mentioned steps but it leads to the same error.

1.My workflow instances list was empty so didn't have to do anything

2.Deleted com.adobe.granite.workflow.transient.job.var.workflow.models.dam.update_asset folder with all child nodes.

3.Restarted my AEM instance.

Still the same error pops in my error.log

@chanakya, thanks for sharing feedback. I am not sure if this issue is happening on your local environment or in some remote server. If it is local then you could try to recreate your AEM instance.

@lukasz-m creating a new AEM instance does work fine but I needed a way around to make the workflow work on my current AEM instance. Thanks for all the help and suggestions. Much appreciated!
