Hi,
I get the following error when a workflow is ran:
Unable to serialize workflow, exception: Type 'System.Workflow.Activities.ReplicatorActivity+ReplicatorInterActivityEventArgs' in Assembly 'System.Workflow.Activities, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' is not marked as serializable.
Any idea what could be causing it?
Greetings,
George

Hi Georgi,
does this happen for all your workflows our just for one? If it happens for all workflows I recommend you try to re-install Nintex. If it still doesn't help, contact support.
If this only happens for one workflow, we have to inspect the workflow itself.
Cheers

Hi,
We managed to find a workaround for the issue this morning. One of our Devs used snippets from another workflow and imported it into this one. When he tried to just recreate the actions in the new workflow everything worked fine.The workflows were on the same site, so there is no reason for the snippets to not work, but they were the reason.
Greetings,

Glad you found a solution! 
I will mark your own answer as correct so others can see that a solution for your issue has been found.
