[Severe] http://127.0.0.1:37189/subdir/WasmMinimal/_content/Microsoft.DotNet.HotReload.WebAssembly.Browser/Microsoft.DotNet.HotReload.WebAssembly.Browser.qp2w4j0l7o.lib.module.js - Failed to load resource: the server responded with a status of 404 (Not Found)

The URL Is correct

• App is hosted on /subdir/
• WasmMinimal client is hosted on /WasmMinimal/ RazorComponentEndpointsStartup.cs#L167

Other framework assets loaded from a similar URLs

• http://127.0.0.1:37189/subdir/WasmMinimal/_framework/dotnet.js

Based on it, the URL for HotReload is generally correct

• http://127.0.0.1:37189/subdir/WasmMinimal/_content/Microsoft.DotNet.HotReload.WebAssembly.Browser/Microsoft.DotNet.HotReload.WebAssembly.Browser.qp2w4j0l7o.lib.module.js

HotReload JS initializer relies on StaticWebAssets manifest, because it is loaded from nuget folder, whereas other framework assets are loaded from bin/wwwroot/_framework folder.

• The folder is correctly mapped in SWA manifest
• The file name including fingerprint matches what's in file system

It doesn't work for UseBlazorFrameworkFiles("/...") as well
