团队协同bug，caught TypeError: Cannot read properties of undefined (reading 'nodeSize')

[sing-jump-rap]

Describe the bug 仿照官方文档"https://www.blocknotejs.org/docs/advanced/real-time-collaboration"中的示例 将"y-webrtc"修改为"y-websocket"，其余部分不变。 用户a编辑文档A并且新建了多个block同时用户b进入文档A就会报这个错误。 如果用户a修改文档后把光标点击到第一个block上，用户b进入文档A就不会报这个错误。 我认为是光标的读取获取存在bug

To Reproduce import * as Y from "yjs"; import { WebsocketProvider } from "y-websocket"; // ...

const doc = new Y.Doc();

const provider = new WebsocketProvider( "wss://demos.yjs.dev", // 官方demo的WebSocket地址 "your-room-name", // 替换为您想要的房间名称 doc ); const editor = useCreateBlockNote({ // ... collaboration: { // The Yjs Provider responsible for transporting updates: provider, // Where to store BlockNote data in the Y.Doc: fragment: doc.getXmlFragment("document-store"), // Information (name and color) for this user: user: { name: "My Username", color: "#ff0000", }, }, // ... });
