我想在反应组件加载后立即将焦点设置在按钮上，以便用户可以仅使用键盘按下按钮。

这就是我试图做的，但这似乎不起作用。

class CustomTextInput extends React.Component {
  constructor(props) {
    super(props);
    // create a ref to store the textInput DOM element
    this.logButton = React.createRef();

  }

  componentDidUpdate(){
     this.logButton.current.focus();
  }

  render() {
    // tell React that we want to associate the <input> ref
    // with the `textInput` that we created in the constructor
    return (
      <div>
        <Button ref={this.logButton}  outline color="primary" size="sm" onClick={this.logManualRequestModal}>
         Log request
        </Button>
      </div>
    );
  }
}

我正在使用tabler-react组件

我在 Dialogflow 履行中使用 firebase admin 版本 6.0.0 发送 fcm 通知。

admin.messaging().send({
    "message": {
        "notification": {
            "title": "Portugal vs. Denmark",
            "body": "great match!"
        },
        "token": user_info.device_id
    }
})
.then((response) => {
    // Response is a message ID string.
    console.log('Successfully sent message:', response);
})
.catch((error) => {
    console.log('Error sending message:', error);
});

这是我收到的错误
