404 Response at helix/channels

Hey Guys
its maybe a little bit off-topic, but I getting 404 Not found at https://api.twitch.tv/helix/channels and https://api.twitch.tv/helix/users. The weird thing is that I only get 404 as status code when I´m using Java but in Python basicly the same request works just fine

Here is my Java Code

public JSONObject getChannel(long id) {
        HashMap<String, String> header = new HashMap<>();

        header.put("Authorization", "Bearer " + TOKEN);
        header.put("Client-Id", CLIENT_ID);

        try {
            return new JSONObject(sendRequest("GET", "https://api.twitch.tv/helix/channels?broadcaster_id=" + String.valueOf(id), header, new ArrayList<AbstractMap.SimpleEntry>()).getJSONArray("data").get(0));
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
            return null;
        }
    }

public JSONObject sendRequest(String method, String url, HashMap<String, String> header) throws IOException, InterruptedException {
        HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
        connection.setRequestMethod(method);

        for (String key : header.keySet()) {
            connection.setRequestProperty(key, header.get(key));
        }

        connection.setUseCaches(false);
        connection.setDoInput(true);
        connection.setDoOutput(true);

        DataOutputStream wr = new DataOutputStream(
                connection.getOutputStream());

        if (connection.getResponseCode() != 200) {
            System.out.println(connection.getResponseCode());
            System.out.println(connection.getResponseMessage());
        }

        InputStream is = connection.getInputStream();
        BufferedReader rd = new BufferedReader(new InputStreamReader(is));
        String line;
        StringBuffer response = new StringBuffer();
        while((line = rd.readLine()) != null){
            response.append(line);
            response.append('\r');
        }
        rd.close();

        return new JSONObject(response.toString());
    }

And the Output is

404 
Not Found

My Python code:

import requests

header = {
    "Authorization" : "Bearer " + TOKEN,
    "Client-Id" : CLIENT_ID
}

res = requests.get("https://api.twitch.tv/helix/channels?broadcaster_id=" + str(ID), headers=header)
print(res.json())

And the python code returns the correct data.

Where is my mistake in the Java Request?

Help is appreciated :slight_smile:
