UploadThing in a backend application

I'm trying to use uploadthing in my Discord Bot, since I don't have any routing or anything complex, I thought that using UTAPI SDK would be enough, but I'm facing a weird error. Whenever I try to use any method provided by UTApi errors with (FiberFailure) TypeError: Attempted to assign to readonly property. Full Error:

I tried using the API but I couldn't understand how to use it.

// @/server/utapi.ts
import { env } from "@/env";
import { UTApi } from "uploadthing/server";

export const utapi = new UTApi({
    apiKey: env.UPLOADTHING_SECRET
});

// @/index.ts
import { utapi } from "./server/utapi";

const url = "https://fastly.picsum.photos/id/604/200/200.jpg?hmac=qgFjxODI1hMBMfHo68VvLeji-zvG9y-iPYhyW0EkvOs";
utapi.uploadFilesFromUrl([url]);

// @/server/utapi.ts
import { env } from "@/env";
import { UTApi } from "uploadthing/server";

export const utapi = new UTApi({
    apiKey: env.UPLOADTHING_SECRET
});

// @/index.ts
import { utapi } from "./server/utapi";

const url = "https://fastly.picsum.photos/id/604/200/200.jpg?hmac=qgFjxODI1hMBMfHo68VvLeji-zvG9y-iPYhyW0EkvOs";
utapi.uploadFilesFromUrl([url]);

So what should I do then? Wait for a fix or use some other workaround? I see you commented saying that using Buffer works fine, but I'm not sure if I should that or not. Btw, I'm okay with using the API but couldn't understand how to use it, is there any content or project example you could recommend? Thanks! :a_shyemoji:

Im afraid waiting for a fix might be the way unfortunately…. That’s kinda life when bleeding on the edge with new stuff. I’ve had to go back to pnpm from bun on a numerous of projects due to weird behaviors and missing features But you should be able to use the native File class unless you need customId prop from UTFile

That's exactly what I did initially, I moved from Bun to PNPM back again, because of some gRPC issues, but realized things are getting better and went back to Bun, now facing another issue :Sad:

julius•7mo ago

Yup :// Been there, done that

FagnerOP•7mo ago

It's a very very very completely idiot solution, but I just removed those lines and gave it a try. It worked but I lost the capability to send these informations, so my files are named in a way I don't want to. I really don't want to use any other service, really like UploadThing.
