Im creating an sveltekit app that fetches json from /static/schemas/{param}.json

The schemas folder will contain hundreds of json files so I really dont want to import it.

Example route: http://localhost:5173/schema/test

[schema]/+page.server.js

export async function load({ fetch, params }) {
    const { schema } = params;
    const schemaFetch = await fetch(`/schemas/${schema}.json`, {
        headers: {
            'Content-Type': 'application/json'
        }
    });

    const json = await schemaFetch.json();
    return {json}
}

Locally http://localhost:5173/schema/test works like a charm, but when I deploy to prod I get 500.

Convox log:

Note: If I try to fetch a non-existing json file, i get error 404.

Any help is deeply appreciated!!

Im using convox for production, and @sveltejs/adapter-node
