Reproduction

https://stackblitz.com/github/martinszeltins/nuxt-proxy-test

Describe the bug

I have a very simple BFF Nuxt setup. I have

1. Server API route server/api/random/user.ts
2. Server route server/random-image/[...path].ts

The API route uses jsonplaceholder to fetch data and the other server route uses proxyRequest to fetch an image from
In my app.vue I fetch my API server route and it works randomwordgenerator.com

Easy enough. But I found that the image route does not work with <NuxtImg> but works fine with regular old <img> 🤔

That's strange. You would expect <NuxtImg> to work just like <img> works. I don't understand why it doesn't work.

When I open my image route in the browser directly it also works just fine 🤷🏻‍♂️ http://localhost:3000/random-image/img/picture-generator/52e5d64a4955a814f1dc8460962e33791c3ad6e04e507440762a7cd59249c0_640.jpg

I am not sure if this is a bug with Nuxt or NuxtImg.

Logs

Start with the linked StackBlitz reproduction, then inspect app.vue and the server routes server/api/random/user.ts and server/random-image/[...path].ts. Compare the generated request from with a regular and with opening the image route directly. Done means the proxy-backed image renders through while the existing API and direct route continue to work.
