BUTTON_NOT_FOUND: comment input not found (page not rendered

Error message

BUTTON_NOT_FOUND: comment input not found (page not rendered, comments disabled, or selectors changed)

What it means

`buildCommentScript` runs in the page to post a TikTok comment: it locates the comment input via `[data-e2e="comment-input"] [contenteditable="true"]` (falling back to any contenteditable). If no input element exists it throws `BUTTON_NOT_FOUND: comment input not found ...`, an in-page Error surfaced by `postComment`. The library treats a missing input as 'cannot comment here' — the page never rendered a comment box.

Solutions

1. Confirm the target video allows comments (check in a normal browser) — disabled comments make this failure permanent for that video.
2. Retry with a longer wait/allow the page to fully load before running the comment script, or re-run the command.
3. Verify the URL resolves directly to the video page (resolve short links like vm.tiktok.com first).
4. Check the live DOM for the comment input selector; if TikTok renamed the attributes, update the library's selectors in buildCommentScript.
5. Ensure you are logged in — logged-out views may not render the comment input at all.

// pre-check: does the video allow comments?
const meta = await fetch(`https://www.tiktok.com/oembed?url=${encodeURIComponent(videoUrl)}`).then(r => r.json()).catch(() => null);
if (!meta) throw new Error('URL is not a resolvable TikTok video');

try {
  await tiktok.comment({ url: videoUrl, text });
} catch (e) {
  if (String(e.message).startsWith('BUTTON_NOT_FOUND') && /comment input/.test(e.message)) {
    // comments disabled / not rendered / selectors changed
    console.warn(`Cannot comment on ${videoUrl}: comments likely disabled or page not loaded.`);
    return { skipped: true, reason: 'comment-input-missing' };
  }
  throw e;
}

When it happens

Trigger: Calling `tiktok comment --url <video>` (postComment -> script) when the video page has comments disabled by the creator, the page didn't finish rendering before the script ran, the URL points to a non-video page (profile/short link that didn't resolve), or TikTok changed the data-e2e attributes/selector structure.

Common situations: Commenting on videos with comments turned off; slow network/first render racing the script; headless rendering stuck on a consent or login wall; TikTok A/B redesign removing `data-e2e="comment-input"`; posting to a deleted/private video.
