Looking for this node

I have several projects that need this node.

The other “Getlayouts” from Camber and Document Extensions cause this error

I don’t see your inputs to this nodes but it Isn’t that node that cause the issue.
You seems to have added the node AutoCad.Document.Block instead of writing the Blockname as a string.
Of you hover over the input you get extra information about the demand of inputs and if there are any predefined values as it is for the input ”Layout”
