Converting from Json String to IDocumentData

Hello,
I am using the document understanding to get data back from a scanned po. What I want to do is create a queue item which will create an task for a human to validate the document. Currently I am Serializing the document data from the scanner into a json string to put in the queue specific content part. In the process (a whole different bot) when I try to deserialize the json back into the IDocumentData object. I am getting this error Assign: Could not create an instance of type UiPath.IntelligentOCR.StudioWeb.Activities.DataExtraction.IDocumentData`1[UiPath.IntelligentOCR.StudioWeb.Activities.SWEntities.ExtendedExtractionResultsForDocumentData.POAcknowledgmentPurchaseOrdersV5.Bundle.POAcknowledgmentPurchaseOrdersV5]. Type is an interface or abstract class and cannot be instantiated. Path ‘Data’.

Has anyone been able to deserialize from a queue specific data into a type of object like this before?

Thanks
