Discord form correction is not current

Error message

Discord form correction is not current

What it means

retainDiscordQuestionFormCorrection validates a Discord modal-based form correction before persisting it. This error means the submitted correction is stale or structurally out of date: the binding has expired, or the modal's callback ID / private metadata no longer match the submit action ID, or the modal has an invalid number of children (Discord requires 1-5 inputs). It prevents replaying or tampering with old form corrections.

Solutions

1. Discard the stale draft and re-issue a fresh question form so a new modal/correction binding is generated
2. Check that the modal's custom_id (callbackId) and private_metadata are both set to the current submitActionId when constructing the modal
3. Ensure the modal has between 1 and 5 child inputs before submitting the correction
4. If expiry is the issue, ask the user to resubmit promptly or extend the binding's expiry window

Example fix

// before
modal.children = sixInputs; // 6 children
// after
modal.children = sixInputs.slice(0, 5); // Discord allows max 5 inputs per modal

function isCorrectionCurrent(input, now) {
  return input.expiresAt > now &&
    input.modal.callbackId === input.submitActionId &&
    input.modal.privateMetadata === input.submitActionId &&
    input.modal.children.length >= 1 &&
    input.modal.children.length <= 5;
}
if (!isCorrectionCurrent(input, Date.now())) return promptFreshForm();

const isCurrentModal = (m) => m && typeof m.callbackId === "string" && m.callbackId === m.privateMetadata && Array.isArray(m.children) && m.children.length >= 1 && m.children.length <= 5;

When it happens

Trigger: Submitting a Discord modal whose expiresAt is in the past; a modal whose callbackId or private_metadata does not equal the submitActionId; a modal built with zero children or more than 5 children.

Common situations: A user takes too long to answer the modal and it expires; a Discord interaction replay/duplicate delivery re-submits an old callback ID; a developer builds a modal with 6+ text inputs, which Discord rejects structurally.
