Как отправить действие изменения в редукционной форме?

Просто изучая редукционную форму, и изнутри моего компонента я пытаюсь изменить имя поля по коду:

Import React from 'react'
import { connect, dispatch } from 'react-redux'
import { Field, reduxForm, formValueSelector } from 'redux-form'



let SelectingFormValuesForm = props => {

  const changeStuff = (props) => {
    dispatch(change('selectingFormValues', 'firstName', 'Bertje'))
  }

  const {
    favoriteColorValue,
    fullName,
    handleSubmit,
    hasEmailValue,
    pristine,
    reset,
    submitting,
    change
  } = props
  return (
    <form onSubmit = {handleSubmit}>
      <div>
        <label>First Name</label>
        <div>
          <Field
            name = "firstName"
            component = "input"
            type = "text"
            placeholder = "First Name"
          />
        </div>
      </div>
      <div>
        <label>Last Name</label>
        <div>
          <Field
            name = "lastName"
            component = "input"
            type = "text"
            placeholder = "Last Name"
          />
        </div>
      </div>
      <div>
        <label htmlFor = "hasEmail">Has Email?</label>
        <div>
          <Field
            name = "hasEmail"
            id = "hasEmail"
            component = "input"
            type = "checkbox"
          />
        </div>
      </div>
      {hasEmailValue && (
        <div>
          <label>Email</label>
          <div>
            <Field
              name = "email"
              component = "input"
              type = "email"
              placeholder = "Email"
            />
          </div>
        </div>
      )}
      <div>
        <label>Favorite Color</label>
        <div>
          <Field name = "favoriteColor" component = "select">
            <option />
            <option value = "#ff0000">Red</option>
            <option value = "#00ff00">Green</option>
            <option value = "#0000ff">Blue</option>
          </Field>
        </div>
      </div>
      {favoriteColorValue && (
        <div
          style = {{
            height: 80,
            width: 200,
            margin: '10px auto',
            backgroundColor: favoriteColorValue
          }}
        />
      )}
      <div>
        <button type = "submit" disabled = {pristine || submitting}>
          Submit {fullName}
        </button>
        <button type = "button" disabled = {pristine || submitting} onClick = {reset}>
          Clear Values
        </button>
        <button type = "button" onClick = {changeStuff}>
          Change first name
        </button>
      </div>
    </form>
  )
}

// The order of the decoration does not matter.

// Decorate with redux-form
SelectingFormValuesForm = reduxForm({
  form: 'selectingFormValues',// a unique identifier for this form
  change: reduxForm.change,
  dispatch:reduxForm.dispatch
})(SelectingFormValuesForm)

// Decorate with connect to read form values
const selector = formValueSelector('selectingFormValues') // <-- same as form name
SelectingFormValuesForm = connect(state => {

  //debugger
  // can select values individually
  const hasEmailValue = selector(state, 'hasEmail')
  const favoriteColorValue = selector(state, 'favoriteColor')
  // or together as a group
  const { firstName, lastName } = selector(state, 'firstName', 'lastName')
  return {
    hasEmailValue,
    favoriteColorValue,
    fullName: `${firstName || ''} ${lastName || ''}`
  }
})(SelectingFormValuesForm)

export default SelectingFormValuesForm

Когда я нажимаю эту кнопку «изменить имя», это выполняется. Я импортировал действие изменения из редукционной формы. Почему я получаю эту ошибку:

react-dom.development.js:283 Uncaught TypeError: (0 , _reactRedux.dispatch) is not a function at changeStuff (SelectingFormValuesForm.js:20) at HTMLUnknownElement.callCallback (react-dom.development.js:143) at Object.invokeGuardedCallbackDev (react-dom.development.js:193)
