This is Vite compilation error. Please, make an issue in Vite repo.

In the meantime, you can rewrite it as:

const baseUrl = import.meta.url
new URL(url, baseUrl)

Although I think it's already fixed: vitejs/vite#8846

You might need to update to Vite 3.0.0-beta.6, or ask Vite team to back port it to Vite 2.
