Cors/render problem

1

Hello, im hosting my express server on render and im facing an issue.
“Access to XMLHttpRequest at ‘https://raftech.adaptable.app/summoner/euw/kaleka’ from origin ‘https://www.rafte.ch’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.”

this problem doesnt occur on my local machine
and im unable to resolve it on my own

const express = require("express");
const axios = require("axios");
const cors = require("cors");
require("dotenv").config();

const app = express();
const PORT = process.env.PORT || 8000;

app.use(cors());

app.get('/summoner/:region/:summonerName/live',cors() ,async (req, res) => {
  try {
    const { region, summonerName } = req.params;
    const { apiRegion } = regions[region] || { apiRegion: region };
    const { data: { id: summonerId } } = await axios.get(`https://${apiRegion}.api.riotgames.com/lol/summoner/v4/summoners/by-name/${summonerName}?api_key=${process.env.RIOT_API_KEY}`);
    const { data: liveResponse } = await axios.get(`https://${apiRegion}.api.riotgames.com/lol/spectator/v4/active-games/by-summoner/${summonerId}?api_key=${process.env.RIOT_API_KEY}`);

    const ranks = await Promise.all(
      liveResponse.participants.map(async (participant) => {
        const { data: livePartic } = await axios.get(`https://${apiRegion}.api.riotgames.com/lol/league/v4/entries/by-summoner/${participant.summonerId}?api_key=${process.env.RIOT_API_KEY}`);
        return livePartic.filter(entry => entry.queueType === 'RANKED_SOLO_5x5');
      })
    );

    res.status(200).json([liveResponse, ranks]);
  } catch (error) {
    console.error(error);
    if (error.response && error.response.status === 404) {
      console.log("No live game found");
      res.json(null);
    } else {
      res.status(500).json({ error: "Internal server error" });
    }
  }
});

Hello there,

I don’t see either of the above domains currently running on Render. The CORS config you currently have would allow requests to be made from any origin, so you shouldn’t see errors like this.

Is either raftech.adaptable.com or www.rafte.ch supposed to be associated with your Render service?

Regards,
Keith
