react-draft-wysiwyg: Uncaught TypeError: editorState.getImmutable is not a function

I’ve got this error whenever I issued any actions with the editor.

Uncaught TypeError: editorState.getImmutable is not a function

Code (unnecessary details omitted)

import {Editor} from "react-draft-wysiwyg";
import {EditorState} from "draft-js"

this.state = {
      detail: EditorState.createEmpty(),
};

onDetailChange(value) {
    this.setState({ detail: value });
    this.props.onChange({ ...this.state, detail: value });
 }

<Editor editorState={this.state.detail} onChange={this.onDetailChange.bind(this)} />
