twitch exporter not returning any metrics

Twitch exporter seems to not collect any metrics nor throw any logs. It also seems to be ignoring some flags as setting --log.level debug results in no extra logs and output seems to confirm so.

[coolapso@nebu]-[~/twitch_exporter]  main go v1.22.5
☸ virt01 ❯go run twitch_exporter.go --log.level debug \
        --twitch.client-id *  \

For this I seem to have no clue where to start looking, would appreciate some help, ill be happy to work on it.

seems to be not returning error properly, added a print just to peak at the response:

func (e *Exporter) Collect(ch chan<- prometheus.Metric) {
    channelsLive := make(map[string]bool)
    streamsResp, err := e.client.GetStreams(&helix.StreamsParams{
        UserLogins: *twitchChannel,
        First:      len(*twitchChannel),
    })
    fmt.Println(streamsResp)
    if err != nil {
        level.Error(e.logger).Log("msg", "Failed to collect stats from Twitch helix API", "err", err)
        return
    }

yelds the following result:

&{{401 map[Content-Length:[69] Content-Type:[application/json; charset=utf-8] Date:[Sat, 20 Jul 2024 14:56:34 GMT] Strict-Transport-Security:[max-age=300] Timing-Allow-Origin:[https://www.twitch.tv] Vary:[Accept-Encoding, Origin] X-Cache:[MISS, MISS] X-Cache-Hits:[0, 0] X-Served-By:[cache-bfi-kbfi7400114-BFI, cache-bma1627-BMA] X-Timer:[S1721487394.244472,VS0,VS0,VE157]] Unauthorized 401 Invalid OAuth token} {[] {}}}

believe this happens because the request is successful therefore err != null ... probably should log if response is not 200
