Good day, I’m having problems with django/ django rest apí

Back:

url(r'^' + baseurl + etl + eph + 'salud_folder_xls/listar/<str:accion>/', etlEPHSaludXLSListar),
   
url(r'^' + baseurl + etl + eph + 'salud_folder_xls/descargar/(?P<nombre_archivo>.+\.xls)', etlEPHDescargarSaludFolderXLS),

Front:

    const response = await axios({
    url: '/etl/v1/eph/salud_folder_xls/listar/',
    method: 'GET',
  });

When I try salud_folder_xls/listar/ works fine
but when I add accion, axios returns always ERROR 404

Any idea?
