Error message

discord: edit message: %w

What it means

discord: edit message wraps an error returned by discordgo's ChannelMessageEditComplex when updating a previously sent streaming preview message fails. The platform uses this call to update the preview card in place as the agent streams output. Any Discord API failure (network, auth, deleted message, rate limit) surfaces wrapped here.

Solutions

1. Check bot permissions in the guild (Manage Messages / Send Messages in that channel)
2. Verify the messageID still exists (not deleted) before editing; fall back to sending a new message on error
3. Validate DISCORD bot token and network connectivity
4. Add retry with backoff for 429/5xx responses

Example fix

// before
_, err := p.session.ChannelMessageEditComplex(buildDiscordPreviewEdit(h.channelID, h.messageID, content))
if err != nil { return fmt.Errorf("discord: edit message: %w", err) }
// after
_, err := p.session.ChannelMessageEditComplex(buildDiscordPreviewEdit(h.channelID, h.messageID, content))
if err != nil {
    if strings.Contains(err.Error(), "404") {
        return p.sendNewMessage(h.channelID, content) // message was deleted; send fresh
    }
    return fmt.Errorf("discord: edit message: %w", err)
}

if handle == nil || handle.messageID == "" { return errors.New("no preview message to edit") }

h, ok := previewHandle.(*discordPreviewHandle); if !ok || h == nil { /* skip edit */ }

_, err := p.session.ChannelMessageEditComplex(edit)
if err != nil {
    if isRateLimit(err) { backoffAndRetry() } else { logAndFallbackToSend() }
}

When it happens

Trigger: Calling UpdateMessage (message edit path, discord.go:1283) with a *discordPreviewHandle whose messageID was deleted, channel perms revoked, token expired, or Discord returning 4xx/5xx/network error.

Common situations: User (or bot cleanup) deleted the preview message mid-stream; bot lost 'Send Messages'/'Manage Messages' permission; invalid or expired bot token; Discord 429 rate limiting during heavy streaming edits.
