I am getting the below error message in line 15 at the file "node_modules/react-mask-field/dist/index.esm.js"

TypeError: k.split is not a function

when I perform this code

export const CardNumberInput = forwardRef<
  HTMLInputElement,
  InputBaseComponentProps
>((props, ref) => {
  const { mask } = props;
  return (
    <MaskField
      ref={ref}
      // mask="____ ____ ____ ____"
      showMask={true}
      replacement={{ _: /\d/ }}
      {...props}
    />
  );
});

type Props = TextFieldProps & {
  mask: string;
  replacement: string | object;
  showMask?: boolean;
};

export const Example = (props: Props) => {
  const { mask } = props;

  return (
    <CustomTextfield
      {...props}
      //inputProps={CardNumberInput}
      InputProps={{
        inputComponent: CardNumberInput,
        inputProps: {
          mask: { mask },
        },
      }}
    />
  );
};

Could you provide more detailed code?
