Validation error : Invalid Item Name

[David_Hernandez2 (David Hernandez)]

First time I have come across this issue, can’t seem to resolve. When I click run/debug, I get a “Unable to start execution” popup.

System.Activities.InvalidWorkflowException: The following errors were encountered while processing the workflow tree:
‘Main’: The private implementation of activity ‘1: Main’ has the following validation error: Invalid Item name

@David_Hernandez2,

Any particular activity throwing this? Also try recreating the workflow activity by activity to isolate the issue.

I found the issue, did what you suggested commented out each activity line by line. Seemed to be coming from this for each:

Item Name being “error” ironically causes this issue to popup. Changing the name to “CurrentError” fixed this issue.

That’s great @David_Hernandez2.

As always, the devil’s in the details

Let’s close the thread!
