The res type of http-proxy-middleware refers to express and res.redirect is express only, but express is not actually used in rsbuild. This is a known issue of http-proxy-middleware v2 and is fixed in v3. Since http-proxy-middleware v2 to v3 has some breaking changes for users, we will think about how to handle it in rsbuild.
