I have started to see the following in the EngagementDesigner log whenever I execute a workflow with my dynamic task. The workflow executes fine and the dynamic task is invoked without any problems. In fact, the error occurs before my dynamic task is even invoked. I verified that by adding a Log Message task before my dynamic task is invoked and the message is in the log after the java crash. The new instance of my task is created at 2016-11-14 13:39:49.

Sure, as you stated, this does not have anything to do with your dynamic task whatsoever.

While instantiating your workflow (starting to run your workflow), it looks like you have a schema in the Start Event that is looking for an "ucid" field in it. But the payload doesn't have it, hence throwing this error. If you look into your workflow, the Start Event schema in there, you may get an idea about where is this ucid, and what is expected there...

If you can post your workflow (.xml), I can look for it and will let you know.

Hi Andrew, this is harmless error. ED is trying to get attributes configured in SMGR based on service profile. In your case there may not have been a call and so ED should not have tried to look up the service profile. This is fixed now in later codes of ED

Thanks. I'll just ignore it. :-)
