Thanks… Work fine after create a computed propìerty for columns

columnsI18n () { let columns = [ { name: 'domain', required: true, label: this.$t('domains.label'), align: 'left', field: row => row.domain, format: val => `${val}`, sortable: true }, { name: 'active', align: 'center', label: this.$t('domains.active'), field: row => row.active, format: val => String(!!val), sortable: true }, { name: 'show', align: 'center', sortable: false }, { name: 'edit', align: 'center', sortable: false }, { name: 'archive', align: 'center', sortable: false }, { name: 'delete', align: 'center', sortable: false } ] return columns }

Well, you can also set up a reverse proxy (openresty/nginx) and have CORS handled at that level. It would solve ALL the problems with EVERYTHING 🙂
Where ALL==every access control request from client, and EVERYTHING==every api/rest/openapi/webservice/endpoint on backend side regardless of used technology (php, python, node, c#, etc.).
