tuitui: channel info errcode=%d errmsg=%s

Error message

tuitui: channel info errcode=%d errmsg=%s

What it means

The TuiTui channel info API (/robot/teams/channel/info) returned a non-zero errcode, so the channel's metadata (team_id, name) could not be retrieved. This function underpins both channel history fetching and SendChannelPost, so both fail when it errors.

Solutions

  1. Read errmsg to identify the backend reason (not-found vs permission vs auth).
  2. Verify the channel_id exists and the bot has access to that channel/team.
  3. Refresh the bot token if the errcode indicates auth failure.
  4. For SendChannelPost failures, check the bot was invited to the channel before posting.

Example fix

// before
if out.ErrCode != 0 {
    return nil, fmt.Errorf("tuitui: channel info errcode=%d errmsg=%s", out.ErrCode, out.ErrMsg)
}
// after
if out.ErrCode == errChannelNotFound {
    return nil, fmt.Errorf("tuitui: channel %s not found or no access: check bot membership", channelID)
}
return nil, fmt.Errorf("tuitui: channel info errcode=%d errmsg=%s", out.ErrCode, out.ErrMsg)
Defensive patterns

Strategy: try-catch

Validate before calling

if channelID == "" { return fmt.Errorf("channel id required") }
// ensure bot invited to channel/team before calling SendChannelPost

Type guard

func (p *Platform) channelAccessible(ctx context.Context, id string) bool {
    _, err := p.getChannelInfo(ctx, id)
    return err == nil
}

Try / catch

info, err := p.getChannelInfo(ctx, channelID)
if err != nil {
    var apiErr *TuiTuiAPIError
    if errors.As(err, &apiErr) && apiErr.IsAuth() {
        if rerr := p.refreshToken(ctx); rerr == nil {
            info, err = p.getChannelInfo(ctx, channelID)
        }
    }
    if err != nil { return fmt.Errorf("cannot access channel %s: %w", channelID, err) }
}

Prevention

When it happens

Trigger: getChannelInfo called by fetchChannelHistory or SendChannelPost where the response body carries out.ErrCode != 0 — typically channel_id not found, bot lacks channel access, or an invalid/expired token.

Common situations: Channel deleted or ID mistyped; bot removed from the channel/team; token refresh lapse; sending a post to a channel the bot was never invited to.
