returned no success evidence

Error message

 returned no success evidence

What it means

assertOkStatus checks that the parsed comment-add response is an object with status === 'ok'. Instagram's web comments API confirms success via this field; any other shape or status means the comment was not posted, so the CLI throws '${label} returned no success evidence'.

Solutions

1. Read the response message field for the specific reason (duplicate, blocked, comments disabled)
2. Deduplicate comment texts and add jitter/delays to avoid spam detection
3. Refresh session cookies / use a less-flagged account if comments are silently rejected
4. Confirm the post allows comments before attempting

Example fix

// before
function assertOkStatus(payload, label) {
  if (!payload || typeof payload !== 'object' || payload.status !== 'ok') {
    throw new Error(label + ' returned no success evidence');
  }
}
// after
function assertOkStatus(payload, label) {
  if (!payload || typeof payload !== 'object' || payload.status !== 'ok') {
    throw new Error(label + ' returned no success evidence: ' + JSON.stringify(payload).slice(0, 200));
  }
}

const payload = await readInstagramJson(r2, 'comment');
if (!payload || typeof payload !== 'object' || payload.status !== 'ok') {
  console.error('Comment rejected:', JSON.stringify(payload));
}

function isSuccessPayload(p) {
  return !!p && typeof p === 'object' && p.status === 'ok';
}

try {
  await runCommentPipeline(args);
} catch (e) {
  if (/no success evidence/.test(e.message)) {
    console.error('Comment not accepted (duplicate, blocked, or comments disabled)');
  } else throw e;
}

When it happens

Trigger: POST /api/v1/web/comments/{pk}/add/ returns 200 with status 'fail', a message like 'commenting is off', a duplicate-comment error, or an unexpected payload shape with no status field.

Common situations: Posting duplicate comments (spam filter); commenting on a post with comments disabled; account temporarily blocked from commenting; shadow-flagged session returning soft-failure bodies.
