Hi,

The snippet you've posted seems to indicate that the system is trying to find a class record named "Error:Can't".  This kind of behavior can sometimes occur when a property or parameter is used to pass the a value, but functionality that populates that value failed.  From the stack trace it looks like an Obj-Open-By-Handle step in the noted activity is failing. I would suggest tracing that activity and looking to see if any properties or parameters are set to "Error:Can't", then tracking back to find out where that property or parameter gets its value.

Hope this helps!
