我使用reactJS 17.0.1和react-bootstrap 1.5.1以及bootstrap 4.6.0
我有一个modal，我想用openModal函数打开，它将状态设置为showModal true，但是当我打开modal时，我在控制台中得到这个错误：

Warning: findDOMNode is deprecated in StrictMode. findDOMNode was passed an instance of Transition which is inside StrictMode. Instead, add a ref directly to the element you want to reference. Learn more about using refs safely here: https://reactjs.org/link/strict-mode-find-node

在网上搜索，我发现很多人都有这个错误，但没有人在构建模型或使用react-bootstrap时遇到这个错误。下面是我为modal编写的代码

<Modal
                    onHide={this.closeModal}
                    backdrop="static"
                    keyboard={false}
                    show={this.state.show}>
                    <Modal.Header closeButton>
                        <Modal.Title>Delete account</Modal.Title>
                    </Modal.Header>
                    <Modal.Body>
                        <p>Are you sure you want to delete this account?</p>
                    </Modal.Body>
                    <Modal.Footer>
                        <Button onClick={(e) => this.closeModal(e)} variant="secondary">Close</Button>
                        <Button onClick={(e) => this.onDeleteHandler(e)} variant="primary">Yes</Button>
                    </Modal.Footer>
                </Modal>

函数(e) => this.onDeleteHandler(e)与模式无关，只是删除帐户并重定向到主页。打开和关闭模式的另外两个函数是防止刷新和将状态设置为false和true。
编辑：我改变了身体的风格，我也更新了模态代码
