Hi,

I have this exception when save a workflow definition. I thought it was my DB but even after I restore my DB from a backup, the exception does not go away.

Can anyone please help.

To serialize an object the object has to have a schema (or inherits from IDictionary or IList) for type:System.Collections.Generic.List`1[[EPiServer.WorkflowFoundation.Workflows.ApproverItem, EPiServer.WorkflowFoundation, Version=6.1.379.0, Culture=neutral, PublicKeyToken=8fe83dea738b45b7]], mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 for base type:EPiServer.WorkflowFoundation.CompiledWorkflowDefinition, EPiServer.WorkflowFoundation, Version=6.1.379.0, Culture=neutral, PublicKeyToken=8fe83dea738b45b7

Best regards,

Nguyen

ApproverItem is used in the approval workflows. Make sure your episerver.config contains an entry for Approval Service as example below:

</externalServices>

</workflowSettings>

The externalService-seting solved the problem for us. Thank you!
