Results of ai analysis 这些日志显示 后端 API 正常工作，没有错误：
后端日志分析
✅ Authorization successful

问题不在后端数据获取，而在前端数据处理。

问题确认
问题不在后端数据获取，而在前端数据处理。
前端 JavaScript 报错发生在这里：
// alerts-rules-builder.tsx:300-305
getAllColumns()
.filter(({ getIsPinned }) => getIsPinned() === false)
.map(({ id, columnDef }) => ({ // 💥 解构时出错
name: id,
label: columnDef.header as string,
...
}))
当某个 column 对象的 columnDef 属性不存在时，解构 { id, columnDef } 会导致后续访问 columnDef.header 报错。

修复方案
需要我帮你修复前端代码吗？修改 alerts-rules-builder.tsx 添加安全检查：
.map((column) => ({
name: column.id,
label: column.columnDef?.header
? (typeof column.columnDef.header === 'function'
? column.id
: column.columnDef.header)
: column.id,
operators: getOperators(column.id),
}))

Hi @NadamHL! I'm Dosu and I'm helping the Keep team. Your analysis is on the right track. I can confirm the vulnerable code in .map(({ id, columnDef }) => ({
name: id,
label: columnDef.header as string, // ⚠️ No null/type check
operators: getOperators(id),
}))This crashes when There have been several related fixes in this area after v0.52.1:
These suggest column state can become inconsistent, leading to the crash you're seeing. I'd recommend upgrading to a newer version where these column handling bugs have been fixed, which may resolve your issue. If you need to stay on v0.52.1, the defensive fix you proposed is reasonable — just note that .map((column) => ({
name: column.id,
label: typeof column.columnDef?.header === 'string'
? column.columnDef.header
: column.id,
operators: getOperators(column.id),
}))To reply, just mention @dosu. Share context across your team and agents. Try Dosu.
