Где ошибка redux?

this.props.updateBrandModels( this.props.changed.filter_models.brands );

		console.log( this.props.brandModels.items )

export const updateBrandModels = (array) => {

	let object = { items: array }

	return {type: 'UPDATE_MODEL_FORM', payload: object};
}

const initialState = {

	items : [ undefined ],

	models : []

	};

const brandModels = (state = initialState, action) => {

	switch( action.type ){

		case "UPDATE_MODEL_FORM":
			return Object.assign({}, state, action.payload );

		case  "UPDATE_MODELS":
			return Object.assign({}, state, action.payload );

		default :  return state;

	}

}

export default brandModels;
