导入已有物料

通过npm 导入[blocknote/react](https://npmjs.com/package/@blocknote/react)这个包，显示导入成功了，然后选择版本进行配置，配置的时候想先简单试试看效果，就简单放了一个输入框在上面（或者完全不进行配置），然后点击保存和预览，一直提示组件构建中
完成后页面会自动刷新,请耐心稍候1-3分钟，但是构建了很久都没有反应，控制台提示et_f.js:7
GET https://losvc.alibaba-inc.com:64556/api/basic net::ERR_CONNECTION_REFUSED et_f.js:7
POST https://losvc.alibaba-inc.com:64556/api/securitytoken net::ERR_CONNECTION_REFUSED，而且看到了请求这个接口https://parts.lowcode-engine.cn/_view/uipaas/query/prototype/buildResult.json?taskId=undefined-componentBuilder-e95c5008-5e81-4691-9620-464b2a5441bf，但是返回内容是"Cannot read property 'message' of undefined"

Reproduce the @blocknote/react import, version configuration, and save/preview flow, then inspect the console requests to /api/basic, /api/securitytoken, and prototype/buildResult.json. Compare the undefined taskId response with the component-builder flow; done means the build completes and preview loads without the connection-refused or undefined-message errors.
