Unable to run in dev mode

Unable to run app in dev mode

When I run yarn tauri:serve on a freshly created vue app it shows blank screen. Instead if I do yarn tauri:build the app loads fine.

To Reproduce

1. Create app using https://github.com/tauri-apps/vue-cli-plugin-tauri
2. Run 'yarn tauri:serve'

Expected behavior

Should load vue app, instead of white screen.

In case anyone gets the blank white screen, what fixed the issue for me is going into file "tauri.conf.json" and changing the line: "devPath": "http://localhost:5000" to the same port my terminal was running to my web browser, which in my case was 8080.
