Query of Nested objects not worcking

Hello there!

I am trying to do a rest api query on a collection using a nested object attribute

/api/tickets?where[order.orderId][equeals]=1363580640437-01

Tickets has this structure

fields: [
        {
            name: 'order',
            label: 'Order',
            type: 'relationship',
            relationTo: 'orders',
            required: true,
            unique: true,
        }
    ],

And orders:

    fields: [
        {
            name: 'orderId',
            type: 'text',
            required: true,
            label: 'ID de Pedido',
        }
              ]
