Deserialize JSON activity


I will have to deserialize json files in UiPath, but I have a some problem. Example file looks like that:

{“Invoice”:{“ID”:3,“NIP”:“111-111-11-11”,“InvoiceID”:“FS 12756/2020”,“IssueDate”:“2020-09-28”,“MPK”:[{"@odata.type":"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",“Id”:33,“Value”:"[530] Shared Services"}]}}

so I can use Deserialize JSON activity and I can read values from InvoiceID,IssueDate etc. by


but if I want read (for example) value from “MPK” by variable(“Invoice”)(“MPK”)(“ID”).ToString I get error. In json file this values in How can I do it ?
