I am currently working with a SharePoint 2013 List Workflow (SPD Workflow).
On my list, I have a custom field called 'Image', which allows user to upload image from the list directly, without needing to upload the image somewhere.
The problem is, when I tried to create a SPD workflow for item approval, the start task process always failed and returned exception:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation
After I checked further into the log, I found the innerException of that error:
The field 'Image' is in a field collection that cannot be updated, such as one returned as part of a query
Is there any workaround on this problem?
