Feather-sequelize $or operator not working

[Arc009]

$or doesn't work in any syntax form. (f.i. https://stackoverflow.com/questions/20695062/sequelize-or-condition-object)

Snippet

const addAssociation = (context) => { const demos = context.app.services['demos'].Model; context.params.sequelize = { raw: false, where: { $or: [{ isVisible: true }, { isValid: true }] }, attributes: { as: 'demos', include: helperDemos } }; delete context.params.query.include; return Promise.resolve(context); };

------------------------------
Server response:
{
    "name": "GeneralError",
    "message": "Invalid value { isVisible: true }",
    "code": 500,
    "className": "general-error",
    "data": {},
    "errors": {}
}

### Expected behavior
The query should perform a simple 'or' operation.

$or is only supported by the Feathers common query syntax passed via params.query. When using params.sequelize you need to use Sequelize operators ([Op.or]: [])
