Sails 1 - Consistency violation: Attempting to tear down a datastore (`default`) which is not currently registered with this adapter

I'm getting the following error when lifting a sails 1 app:

Consistency violation: Attempting to tear down a datastore (default) which is not currently registered with this adapter. This is usually due to a race condition in userland code (e.g. attempting to tear down the same ORM instance more than once), or it could be due to a bug in this adapter.

I have absolutely no clue what this error means. This is how my config files look like:

Category.js (Model)

module.exports = {
    schema: true,
    attributes: {
        name: {
            type: 'string',
            required: true,
            unique: true
        },
        products: {
            collection: 'product',
            via: 'category'
        },
        parentCategory: {
            model: 'category',
            defaultsTo: null
        },
        ancestors: {
            type: 'json',
            columnType: 'array',
            defaultsTo: []
        }
    }
};

datastores.js

module.exports.datastores = {
default: {

    adapter: require('sails-mongo'),
    host: 'localhost',
    port: 27017,
    // user: 'username',
    // password: 'password',
    database: 'your_mongo_db_name_here'

}


};
