Hi All,

We have upgraded our AEM instance from 6.3 to 6.5 and everything went smoothly but the out of box workflow "DAM Update Asset" is not starting at all and throwing the below exception on error.log file. Can you please anyone look into this issue as it final stage of Go Live. 

Exception in error.log
