Failed to Load Source Maps via DevTools

[KiddoV]

Is anyone has this experience like me?

I am using lot of third party libraries for my app, and whenever I get error from any third party lib, I cannot trace where the error came from.
When clicking the link in DevTools I cannot open the source code, instead it will say something like:

Could not load content for http://wails.localhost:34114/node_modules/.vite/deps/null (HTTP error: status code 504, net::ERR_HTTP_RESPONSE_CODE_FAILURE)

I am using svelte-ts template with vite. I have tried using vite build.sourcemap = true or build.sourcemap = 'inline', but it doesn't work.

Please help!
