Create PDF teamplate for Intervention

How do I get my new model to appear here? I’m following the: https://wiki.dolibarr.org/index.php/Create_a_PDF_document_template where he informs it to be inserted in the table: llx_document_model, I inserted the data but the model does not appear in this place only when I create an intervention, however when this error is selected: Error Failed to load doc generator with modelpaths = core / modules / fichinter / doc / - model = idear.
