Error message

interaction followup edit failed ({status}): {err}

What it means

discord_edit_interaction_response PATCHes the deferred interaction's @original message via {api_base}/webhooks/{app_id}/{token}/messages/@original, carrying the first ≤2000-char chunk plus embeds and action rows (called from deliver_interaction_answer in the send() path for interaction: recipients). Non-2xx becomes this error. Typical causes: interaction token expired (15-minute lifetime), the @original placeholder deleted by a user, or 50035 Invalid Form Body from embed/component violations (total embed length >6000, invalid component structure, empty content with no embeds).

Solutions

1. Match the embedded status: 404/Unknown interaction → token expired; 10008 Unknown Message → placeholder deleted; 400 50035 → payload validation
2. Finish interaction answers well inside 15 minutes — run long tools after delivering the answer
3. On deleted @original, fall back to posting a fresh followup message (the webhook accepts new messages)
4. Clamp embed sizes and validate component markers before delivery

Example fix

// before: only the @original edit
discord_edit_interaction_response(&client, app, tok, base, content, &embeds, &rows).await?;

// after: fall back to a followup post when @original is gone
if discord_edit_interaction_response(&client, app, tok, base, content, &embeds, &rows).await.is_err() {
    discord_post_interaction_followup(&client, app, tok, base, content).await?;
}

if discord_edit_interaction_response(&client, app, tok, base, content, &embeds, &rows).await.is_err() {
    // @original gone or token dead — a fresh followup still works while the token lives
    discord_post_interaction_followup(&client, app, tok, base, content).await?;
}

When it happens

Trigger: Agent turn exceeding 15 minutes before the final edit; user deleting the "thinking…" placeholder first; [EMBED:...] payloads exceeding embed limits after prepare_outgoing_embeds; [COMPONENTS:...] markers producing invalid rows; empty content with no embeds/components.

Common situations: Slow agent pipelines (long tool runs) blowing the token TTL; users dismissing the deferred state; oversized embed descriptions or images; marker output from newer templates against stricter validation.
