Fade Error when using <Message> Component

[nick-ma]

I encountered with errors when I use <Message> component within <MessageList>. I've traced down to the ui-kit source code, and found the following lines:

		var message = React.createElement(
			Toggle,
			null,
			function (_ref2) {
				var authorOpened = _ref2.on,
				    getElementTogglerProps = _ref2.getElementTogglerProps;
				return React.createElement(
					StyledMessage,
					_extends$3({}, getElementTogglerProps(props), { own: isOwn, tabIndex: null }),
					React.createElement(
						Content,
						null,
						React.createElement(
							reactTransitionGroup_2,
							null,
							(!showMetaOnClick || authorOpened) && React.createElement(
								Fade,
								null,
								React.createElement(
									MessageMeta,
									null,
									authorName && React.createElement(
										AuthorName,
										null,
										authorName,
										' '
									),
									date && React.createElement(
										Time,
										null,
										date
									)
								)
							)
						),
						children,
						deliveryStatus && React.createElement(
							Status,
							null,
							deliveryStatus
						)
					)
				);
			}
		);

and the definition of Fade

var Fade = function Fade(_ref) {
	var children = _ref.children,
	    props = objectWithoutProperties$1(_ref, ['children']);
	return React.createElement(
		reactTransitionGroup_4,
		_extends$3({}, props, { classNames: fade, timeout: 200 }),
		children
	);
};

Fade.propTypes = {
	children: PropTypes.node
};

I don't know what goes wrong, I need your help, thx.

react-dom.development.js:55 Uncaught Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of `Fade`.

UPDATE： I add showMetaOnClick prop to Message, and it finally shows me the correct page, however, when I click the message, the same error occurs.
