Editable Grid with a record type

Hi 

So basically, i have a record type for " Requests" and i have another record type for "Documents ", In the "Add or Create Request" Interface, which was generated by record action, I should include a section for "Adding Documents", except that adding a document should be done by an editable grid and not record action. 

I have the following code for the document editable grid, but when i link it to the document error I keep getting the error shown in the image below. 

what is the right way to link the editable grid to the document record type? 

, 

   a!gridLayout(
        totalCount: count(local!document),
        headerCells: {
          a!gridLayoutHeaderCell(label: "Document" ),
          a!gridLayoutHeaderCell(label: "Name" ),
          a!gridLayoutHeaderCell(label: "Classification" ),
          a!gridLayoutHeaderCell(label: "Uploaded By" ),
          a!gridLayoutHeaderCell(label: "Uploaded On" )
        },
        columnConfigs: {
          a!gridLayoutColumnConfig(width: "DISTRIBUTE", weight:3 ),
          a!gridLayoutColumnConfig(width: "DISTRIBUTE", weight:3 ),
          a!gridLayoutColumnConfig(width: "DISTRIBUTE", weight:3 ),
          a!gridLayoutColumnConfig(width: "DISTRIBUTE", weight:3 ),
          a!gridLayoutColumnConfig(width: "DISTRIBUTE", weight:2 )

        },
        rows: a!forEach(
          items: local!document,
          expression: a!gridRowLayout(
