Ошибка в KeyboardDatePicker Material-UI React

Хочу подключить KeyboardDatePicker от Material UI в Next.js приложении. Беру следующий код из примера:

import "date-fns"
import DateFnsUtils from "@date-io/date-fns"
import classNames from "classnames"
import PropTypes from "prop-types"
import { makeStyles } from "@material-ui/core/styles"
import {
  MuiPickersUtilsProvider,
  KeyboardDatePicker,
} from "@material-ui/pickers"

const useStyles = makeStyles({})

const CustomDatePicker = (props) => {
  const classes = useStyles()

  const dateOfBirth = new Date()

  return (
    <MuiPickersUtilsProvider utils={DateFnsUtils}>
      <KeyboardDatePicker
        id="childDateOfBirth"
        disableToolbar
        variant="inline"
        format="MM/dd/yyyy"
        margin="normal"
        value={dateOfBirth}
        KeyboardButtonProps={{
          "aria-label": "change date",
        }}
      />
    </MuiPickersUtilsProvider>
  )
}

export default CustomDatePicker

Появляется такая ошибка:

RangeError: Format string contains an unescaped latin alphabet character `n`

Никак не могу понять в чем причина. Библиотека @date-io/date-fns и фреймворк Next.js несовместимы?
