How to find out what Workflow an Activity Error is from?

Workflow
Updated April 15, 2022
asked on April 13, 2022

I am looking at the Activity Errors log in the Workflow Administration Console and when I look at an error that is listed, it does not specify which workflow the activity belongs to that is throwing the error. What is the best way to figure that out so I can troubleshoot the problem?

If you look at the stack trace, it should have something like this:

 <Property name="ActivityName">MoveEntry</Property>
 <Property name="ActivityType">Laserfiche.Workflow.Activities.MoveEntry.MoveEntryTaskActivity</Property>

If it does, the log viewer should pull it into the Activity Name column. If it doesn't, it might've happened somewhere in a subsystem where we didn't have the activity name.

Paste the stack trace in here and we'll help you read it.

Thanks Miruna! I won't be as involved with Laserfiche as I have been, but it will still be nice to be part of the community.

Below is the stack trace from the error:

Ah, SDK scripts. That message seems to be missing the instanceID property. I'll double-check if that's a bug or if that info is not accessible to the task subsystem.

If you go to the Designer and search for workflows terminated with "time of last action" around 4/13/2022 12:49:58 PM, you should be able to narrow it down to only a few instances to check for an SDK Script activity called "SDKScriptAssignTags "

We were able to find the workflow that contained the activity in question. Please let me know if not showing the instanceID is a bug or not. It would be great if there was a simpler way to track it down.

Dude, you can't just roll in here and ask questions all nonchalant without updating your goodbye post. Glad you'll still be around! And that you got to keep all those sweet Laser Points you earned with your previous account.

You hit 10,000 points, we bend some rules when you make requests wink (seriously though, we will merge accounts when people change jobs, if requested).
