Context:

I'm trying to fetch datas from an ended crowdloan. The crowdloan is on kusama, for parachain id 2113.

installed api with:

yarn add @polkadot/api

So, I first connect:

import { ApiPromise, WsProvider } from '@polkadot/api';

async function connect() {
    let endpoint = config.endpoint;
        global.endpoint = endpoint;
        const provider = new WsProvider('wss://kusama-rpc.polkadot.io');
        const api = await ApiPromise.create({
            provider,
        });
        return api;
}

then fetch the addresses of the users that contributed:

async function fetchCrowdloan() {
    try {
        const api = await connect();

        console.log(await api.derive.crowdloan.contributions(2113))
        process.exit(0)
        // other stuff
    } catch (error) {
        console.log(error)
        process.exit(1)
    }
}

fetchCrowdloan()

Yesterday, when i ran my script, an array of the 478 users i expected to be here, was logged in the terminal. I closed my PC, went to sleep, and this morning, it doesn't work anymore, I get this error when running node myscript.js:

How can i solve it ? All of the other calls are working fine, it's really just the contribution() function
