Believe it or not, You can just use String.indexOf function in your case Because

By definition, String LIKE %word% means if the String contains word:

router.get('/booking-information', function (req, res) {
  // Get orders
  Promise.all([
    Order.findAll({
      /*where: {
        endDate: null,
      },*/
      order: [
        ['id', 'DESC'],
      ]
    }),
    Professional.findAll({
      where: {
        status: '1'
      }
    })
  ])
    .then(([orders, professionals]) => {
      orders.map((order) => {
        let professionalsInSameArea = professionals.filter((professional) => {
          return (professional.service === order.service 
                 || (professional.secondary_service || '').toLowerCase().indexOf((order.service || '').toLowerCase()) > -1) 
            && (professional.area === order.area 
                || order.area === professional.secondary_area);
        });
        order.professionals = professionalsInSameArea; //you don't need to spread, then make an array
        return order;
      });
      res.render('booking-information', { title: 'Technician', orders: orders, user: req.user });
    })
    .catch((err) => {
      console.error(err);
    });
});

you can use Op operator in query
like :-

const Op = Sequelize.Op

{
  [Op.or]: [
    {
      fieldName: {
        [Op.like]: 'abc%'
      }
    },
    {
      fieldName: {
        [Op.like]: '%abc%'
      }
    }
  ]
}
