Feathers-Sequelize with Postgres: How to query an Array

I want to see if an array contains one or more values inside it.

This is a model field definition:

 keywords: {
              type: Sequelize.ARRAY(Sequelize.STRING),
              defaultValue: [],
              allowNull: false,
           },

This is the query I am testing:

context.app.services.jobOffers.Model.findAll({
        where: {
            keywords: {
                $contains: ['hello'],
            },
        },
    })
     .then(result => {
         console.log('RESULT:', result)
     })
     .catch(err => {
            console.log('ERROR:', err)
     })

This is the error I am receiving: 

ERROR: TypeError: values.map is not a function

This is a reference to a similar issue, where I tried to replicate the solution but to no effect.

It seems the issue was with the Sequelize versions. This was made clear to me by one of the authors of Feathers.js @daffl

"In Sequelize v5 and later you need to use Symbols like [Op.contains] see (http://docs.sequelizejs.com/manual/querying.html#operators)"

So the fix is to change this line of code

where: {
         keywords: {
          [Op.contains]: ['hello'],
         },
       },
