Blurhash isn't being generated for local images in Astro

[carlos-dubon]

Describe the bug
Blurhash isn't being generated for local images in Astro.

To Reproduce

---
import { Image } from "@unpic/astro";
import localImage from "@assets/img/my-local-image.jpeg";

This works and generates a blurhash
<Image
      src=''https://images.unsplash.com/photo-1496128858413-b36217c2ce36?ixlib=rb-4.0.3&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=256&h=256&q=80"
      alt="Remote image"
      width={256}
      height={256}
      placeholder="blurhash"
 />

This doesn't generate a blur has:
<Image
      src={localImage}
      alt="Local image"
      width={256}
      height={256}
      placeholder="blurhash"
 />

This is my astro config:

// @ts-check
import { defineConfig } from "astro/config";
import tailwindcss from "@tailwindcss/vite";
import { imageService } from "@unpic/astro/service";
import react from "@astrojs/react";

import mdx from "@astrojs/mdx";

// https://astro.build/config
export default defineConfig({
  vite: {
    plugins: [tailwindcss()],
  },
  image: {
    service: imageService({
      placeholder: "blurhash",
    }),
  },
  integrations: [
    react({
      experimentalReactChildren: true,
    }),
    mdx(),
  ],
  experimental: {
    svg: true,
  },
});
