为什么不在 Node.js Express 项目中对路由使用 .Flash 和 .Redirect Fire？

Question

我正在使用 flash widely in my Node.js Express application, but for one route I can't get flash or redirect to work. Views are with pug:

form.permissive(action=`/setPermissive/${device._id}/${device.allowUnlock}` method="POST")
  label.groupTitle(for="setPermissive") Allow Unlock
    button.switch(type="submit" name="setPermissive")
      label.switch
        if (device.allowUnlock)
          input(type="checkbox" name="setPermissive" checked)
        else
          input(type="checkbox" name="setPermissive" )
        span.slider

路线：

router.post('/setPermissive/:id/:permissive', catchErrors(deviceController.changePermissive));

控制器：

exports.changePermissive = async (req, res) => {
  const permissive = (req.params.permissive === "false") ? false : true;
  const device = await Device.findOneAndUpdate({ _id: req.params.id },  { $set: { allowUnlock : !permissive } }, {
    new: true
  }).exec();
  req.flash('success', `Successfully updated ${device.name}`);
  res.redirect('/devices');
};

我知道 Device.findOneAndUpdate 执行，因为我可以在后端看到它，但我没有收到闪现消息，我没有被重定向，UI 没有反映更新。如果我手动刷新页面，我会收到闪现消息并且 UI 已更新。

我有类似的路由，可以按预期进行闪烁和重定向，例如：

form.form(action=`/changeStatusEnabled/${device._id}/${newStateEnabled}` method="POST")
  input.button(type="submit" value=`${currentStateEnabled}` onclick=`return confirm('${msgConfEnabled}');`)

router.post('/changeStatusEnabled/:id/:state', catchErrors(deviceController.changeStatusEnabled));

exports.changeStatusEnabled = async (req, res) => {
  const myBoo = (req.params.state === "enable") ? true : false;
  const device = await Device.findOneAndUpdate({ _id: req.params.id }, { $set: { isEnabled: myBoo }}, {
    new: true
  }).exec();
  req.flash('success', `Successfully updated ${device.name}`);
  res.redirect(`/devicesAdmin`);
};

我错过了什么？

出于某种原因，.permissive class 导致打嗝。如果有人知道为什么，我洗耳恭听。

已更改：

form.permissive(action=`/setPermissive/${device._id}/${device.allowUnlock}` method="POST")
  label.groupTitle(for="setPermissive") Allow Unlock
    button.switch(type="submit" name="setPermissive")
      label.switch
        if (device.allowUnlock)
          input(type="checkbox" name="setPermissive" checked)
        else
          input(type="checkbox" name="setPermissive" )
        span.slider

至：

form(action=`/setPermissive/${device._id}/${device.allowUnlock}` method="POST")
  label.groupTitle(for="setPermissive") Allow Unlock
    button.switch(type="submit" name="setPermissive")
      label.switch
        if (device.allowUnlock)
          input(type="checkbox" name="setPermissive" checked)
        else
          input(type="checkbox" name="setPermissive" )
        span.slider
