I’m getting an error message in dynamo when I try to write “List.GetItemAtIndex” it seams like some bug with archi-lab packadge, or I’m typing it wrong, can someone help? and I just can’t get anything from the node.

Thanks

Hi @Jose_Goncalves

It happens when you have to many custom packages. Add “DSCore” (Design Script Core) to call function from the DS.
