Unable to open invoice!

[0xrpj]

I generated the invoice in the backend as such:

async function generateLink() {
    const payload = {
        title: "TG Game",
        description: "TG Game is a fun game",
        uuid: randomUUID(),
        provider_token: '',
        currency: 'XTR',
        prices: [{ label: "TGGame", amount: 1 }]
    }

    console.log(payload)

    try {
        const url = `https://api.telegram.org/bot${process.env.BOT_TOKEN}/createInvoiceLink`;
        const response = await axios.get(url, {
            params: {
                title: payload.title,
                description: payload.description,
                payload: payload.uuid,
                provider_token: '',
                currency: 'XTR',
                prices: JSON.stringify(payload.prices),
                photo_url:
                    "https://upload.wikimedia.org/wikipedia/en/thumb/5/5f/Original_Doge_meme.jpg/220px-Original_Doge_meme.jpg",
                photo_width: 500,
                photo_height: 500,
            },
        });

        return response.data.result;
    } catch (e) {
        console.log({ e })
        return ''
    }
}

In the frontend, I am using this package and here is the code:

import { useLayoutEffect } from 'react';
import WebApp from "@twa-dev/sdk";

function App() {

  useLayoutEffect(() => {
    const initWebApp = async () => {
      if (typeof window !== "undefined") {
        WebApp.ready();
      }
    };

    initWebApp();
  }, []);

  function openInvoice() {
      WebApp.openInvoice("https://t.me/$KUjyOab64FUKAQAAVP4zD7wA1QU", (data) => {
      console.log({ data })
    })
  }

  return (
    <>
      <h1>TG Stars Demo</h1>
      <div className="card">
        <button onClick={() => { openInvoice() }}>
          Buy Stars
        </button>
      </div>
    </>
  )
}

export default App

But, I keep getting "An error occured". And the callback function says failed and for the love of god, I don't know why.

Its not a problem with my account. I have tried paying in other apps and it did work.
