Supabase Auth + FastAPI 集成有三个常见坑:JWKS 路径不是标准路径、ES256 签名需转换为 DER 格式、用户首次登录时本地数据库无记录。本文提供完整解决方案。
在 RAG 知识库项目中调试混合检索评分问题,以下是完整排查过程。
Milvus 混合检索的加权融合分数 = 0.7 * dense_score + 0.3 * sparse_score,理论最大值约 0.7。如果用 min_similarity=0.7 过滤,结果几乎全被剔除。解决方案:将阈值降到 0.3,或根据融合策略动态调整。
在 RAG 知识库项目中调试查询结果返回格式问题,以下是完整排查过程。
RAG /query 接口返回的 sources 字段只包含 metadata,没有每条来源的 similarity 分数。解决方案:在组装响应时,将 metadatas 和 distances 合并,计算 similarity = 1 - distance。
Frontend code pushed to Git but new feature missing on production? The root cause is usually outdated build artifacts on the server. Compare local and server dist/ directory timestamps to confirm, then run npm run build on the server.

Milvus 混合搜索(Dense + Sparse)有四个常见坑:空稀疏向量报错、Collection 未加载、sparse 格式错误、阈值过高。本文给出每个问题的最小修复代码。
Encountered this issue while upgrading Node.js version for an enterprise SaaS system. Documenting the root cause and solution.
Node.js v24 changed Web Crypto API implementation. The jose library now requires keys to be KeyObject or CryptoKey type. Wrap your key with crypto.createSecretKey() to fix.
Module-level const URL = process.env.SERVICE_URL executes before dotenv loads, resulting in undefined. Use getter functions const getUrl = () => process.env.SERVICE_URL for lazy evaluation.
In Docusaurus i18n sites, using <a href="/docs/xxx"> absolute paths in English pages redirects to Chinese. Solution: Use <Link to="/docs/xxx"> for page components, and relative paths ./xxx in MD documents.
Add multiple @docusaurus/plugin-content-blog instances in the plugins array, each with different id, path, and routeBasePath.
