Seeing as your DADOS node has only one item output, and the node your referencing has multiple, the first item works, but the subsequent items 2-11 are looking for items 2-11 on the DADOS node which don’t exist (undefined).
If your n8n version is new enough you can use the new magical item linking
$('DADOS KUTT').item.json.urlBaseNova which should know that each of those 11 items in Set1 relate to item 1 in the DADOS node.
The alternative, if the DADOS node will only ever output a single item is to use $('DADOS KUTT').first().json.urlBaseNova, or $('DADOS KUTT').itemMatching(0).json.urlBaseNova. The old version of this was $item(0).$node['DADOS KUTT'].data.urlBaseNova
