`send_card` is only in-thread while `send_stream_request` is only in-channel

[torgeirl]

send_card (and send_stream_request) used to not reply in-thread (Errbot #1549), but within the last few months send_card is suddenly only reply in-thread when invoked.

As noted by @nzlosh this repo have recently made changes to its send_card implimentation:

This sounds specific to the slack backend, which was patched to reply to threads here errbotio/err-backend-slackv3#76

Do you mind opening an issue under the slackv3 repository please?

Had another look at this after upgrading to Errbot 6.2.0, and when attempting to provide card.parent, as exemplified by @TheJokersThief in #76 ...

@botcmd
def hello(self, msg, args):
    """Say hello to someone"""
    return_msg = Card(
        to=msg.frm,
        title="Hello, world",
        parent=msg.parent if msg.parent else None,
    )

    self._bot.send_card(return_msg)

... I get an error stating that send_card() doesn't have a parent keyword argument:

Traceback (most recent call last):

Trying to only use card.to (instead of card.in_reply_to as instructed in the docs) gives a similar error:

As a side note it seems strange that the default behavior of send_card() isn't similar to send_message(): only reply in-thread when prompted in a thread.

Also note that send_card() and send_stream_request() have the opposite behavior:

• send_message() replies in either channel or thread (where prompted) ✔️
• send_card() always reply in-thread ❌
• send_stream_request() always reply in channel ❌
