"Failed to parse webhook URL" when using webhook inside thread

[hatkidchan]

I was planning to bridge messages into a thread instead of separate channel using https://discord.com/api/webhooks/${channel_id}/${token}?thread_id=${thread_id} link, but it failed to start server with the following exception:

Unfortunately, threads are not yet supported. We'd have to look into that first.
