Solutions

1. Restart pagination from page 1 to regenerate the cursor.
2. Ensure cursors originate only from server responses.
3. Validate/normalize date strings before persisting them.

function isValidCursorDate(v: unknown): boolean {
  if (typeof v !== 'string' && typeof v !== 'number' && !(v instanceof Date)) return false;
  return !Number.isNaN(new Date(v).getTime());
}

When it happens

Trigger: A cursor date field that is a string like "not-a-date" or a malformed/truncated ISO string, or a number that is not a valid epoch timestamp.

Common situations: Truncated ISO string in a cached cursor; locale-formatted date slipped in; non-numeric garbage typed into the field; stale cursor across a format change.
