Labels are not applied to issues created by Utterances

I have integrated Utterances like this:

    <script src="https://utteranc.es/client.js"
            repo="thomaslevesque/blog"
            issue-term="pathname"
            label="post-comment"
            theme="github-light"
            crossorigin="anonymous"
            async>
    </script>

It works fine, except that the post-comment label is not applied to issues. It worked the first time I tried it (see this issue – there isn’t actually a comment because I deleted it), but since then Utterances never applied the label.

Note: the only time it worked, I was the one commenting. Could this be because I’m the repo owner?

@phil-opp very good point! Maybe the label should be specified in utterances.json instead In fact, the same is true of other parameters, like issue-term.

OK, I’m not sure I understand everything in the code, but I think I might be onto something…

The issue is created by @utterances-bot, which is authenticated with its own token, like this:

https://github.com/utterance/utterances-oauth/blob/d7d294461a01d902005a5c7b511eb23db07aa6d9/src/routes.ts#L199

However, to apply the label, utterances uses the commenter’s authorization header, like this:

https://github.com/utterance/utterances-oauth/blob/d7d294461a01d902005a5c7b511eb23db07aa6d9/src/routes.ts#L211

So, it uses the commenter’s identity to apply the label, which probably fails because that user doesn’t have permissions to apply the label. I suspect that the error is somehow swallowed by fetchEvent.waitUntil.

Anyway, maybe the fix is as simple as using 'token ' + settings.bot_token instead of authorization, to apply the label under the identity of @utterances-bot?

I’m not sure if that makes sense… I don’t know Typescript very well.
