Could you include an example of what the botcmd you were using to do this? If it's a custom botcmd, would also be able to include a snippet of it?

I have the same issue. My botcmd looks something like this

@arg_botcmd("job_id", type=int, name="get-jenkins-log")
def get_jenkins_log(self, msg, job_id):
    try:
        to = msg.frm.room
    except AttributeError:
        to = msg.frm

    body = Command.get_jenkins_job_log(job_id)

    self.send_stream_request(
        user=to,
        fsource=BytesIO(
            bytes(
                body,
                "utf-8",
            )
        ),
    )

The issue seems to be that to.channelid contains <#C12345|channel-name> instead of just C12345 that Slack expects. In my case the fix is changing stream.identifier.channelid to stream.identifier.id in _slack_upload

def _slack_upload(self, stream: Stream) -> None:
    """
    Performs an upload defined in a stream
    :param stream: Stream object
    :return: None
    """
    try:
        stream.accept()
        resp = self.slack_web.files_upload(
            channels=stream.identifier.id, filename=stream.name, file=stream
        )
        if resp.get("ok"):
            stream.success()
        else:
            stream.error()
    except Exception:
        log.exception(f"Upload of {stream.name} to {stream.identifier.channelname} failed.")
