Description
我发现在使用从 OJ 中导入队伍时，会有报错：
简单阅读源码后，大致定位问题可能来自 fetcher.ts，293 行的这一段代码：
Hydro 同步队伍时，把带 _id 的整条 team 直接塞进了 set，似乎是导致这个报错的原因。
for (const team of teams) {
const logo = resolvePublicAssetUrl(team.schoolLogo || team.logo || team.avatar, config.server);
await this.ctx.db.teams.update({ id: team._id }, {
$set: {
...team,
...logo && { logo },
},
}, { upsert: true });
}
修改后问题也成功解决了：

Research direction
Start in fetcher.ts around line 293 and follow the team import path used by “Load from OJ”. Reproduce the team synchronization error, then verify that the database update no longer attempts to write the imported team’s _id and that the import completes successfully.
