we should filter the shaked plugin , and it's content should not be false, otherwise the runtime will throw error

like this?

    this.options.plugins = this.options.plugins.reduce((res, plugin) => {
      if(!plugin) return res;
      if (res && !res.find((item) => item.name === plugin.name)) {
        res.push(plugin);
      }
      return res;
    }, pluginRes || []);
    ```
