嗨，我正在尝试在 react-bootstrap 中导入模式弹出窗口，但它显示以下错误：Props not defined> 我从 react-bootstrap 文档中获取了它，但无法理解错误

/src/components/AddProcessModal.js
  Line 24:28:  'props' is not defined  no-undef

这是代码：

export class AddProcessModal extends Component {
  constructor(props) {
    super(props);
  }

  render() {
    return (
      <Modal
        {...this.props}
        size="lg"
        aria-labelledby="contained-modal-title-vcenter"
        centered
      >
        <Modal.Header closeButton>
          <Modal.Title id="contained-modal-title-vcenter">Add KPI</Modal.Title>
        </Modal.Header>
        <Modal.Body>
          <div className="container">Add KPI Fields for BPMS</div>
        </Modal.Body>
        <Modal.Footer>
          <Button onClick={props.onHide}>Close</Button>
        </Modal.Footer>
      </Modal>
    );
  }
}
export default AddProcessModal;
