- Check you have a `onError` bound to catch errors

- Check you have enabled the config service (image taken from a released extension only because I already had the page open)

- Check you are running `.set` from a config panel, or when it’s the broadcaster connected

`This function can be called by the front end to set an extension configuration. It uses the Twitch-provided JWT for broadcasters, to allow broadcasters to set a broadcaster configuration segment.`

</div>

the problem was in the documentation, because the function name is written in lowercase

`twitch.configuration.set`

but this doesn’t work, for it to work you must capitalize the first letter of “Twitch”

`Twitch.ext.configuration.set`

Yeah a lot of the docs expect you to have case a

```
const twitch = window.Twitch

```

I think we have uservoices in place to make adjustments
