Where is the redux error?

Question

JavaScript

I have js code

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

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

everything is updated in the redux console

, but when I output the array data immediately after the method to the console, the action
code is empty there

export const updateBrandModels = (array) => {

  let object = { items: array }

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

reducer code

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;
