AEM 6.3:

I tried to start out of the box "Update DAM Asset" workflow and it seemed to go fine until I saw following in the logs.

Custom application workflows are giving "Could not start workflow" and workflows are not even starting.

I logged in as "adminstrator" and has all the permissions on workflow nodes.

Thanks,

AEM 6.3 with CFP.

Custom application workflows - "Could not start workflow" alert coming and workflow never triggered.

OTB workflow "Update DAM Asset" throwing above exception in logs on all dam assets.

Are you seeing this error for any particular set of Assets ? When you start  your custom application workflows , what exact error are you getting in the logs ? Is it logging something ?

Which AEM version are you using?
