Vite returns 502 in the default setup for tauri window, but not for web browser

[liquidhelium]

System Info: Arch Linux, kernel 6.15.4-arch2-1.

With webkit2gtk-4.1 installed via yay.

I created a new project using yarn create tauri, selected Typescript+React.
When I run yarn tauri dev, Tauri window show a blank screen:

As the image shown, there's no dom elements. Refreshing the page shows the following error in the console:

However, it worked fine inside web browsers.
Common workarounds didn't worked for me, including WEBKIT_DISABLE_COMPOSITING_MODE=1 AGENTS=1. (It was for those whose dom are correct, but I tried nevertheless)

Could anyone identify the problem?
