Summary

Webhook.send() doesn't accept thread=None

Reproduction Steps

thread=None cannot be used in Webhook.send() method. It is useful when I want to send a message to a channel/thread (code doesn't know which one).

Minimal Reproducible Code

dst = some_channel
webhook = await (dst if not isinstance(dst, Thread) else dst.parent).create_webhook(name='webhook')
await webhook.send(content='something', thread=None if not isinstance(dst, Thread) else dst)

Expected Results

Works.

Actual Results

  File "/data/project/rv/pyvenv/lib/python3.13/site-packages/discord/webhook/async_.py", line 1898, in send
    thread_id = thread.id
                ^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'id'
