threads.text.required - letmepost.dev

What it checks

If media is empty or absent, text.trim().length > 0. Threads supports four post shapes:

Text-only: text required, no media.
Single image: text optional, one image.
Single video: text optional, one video.
Carousel (2–20): text optional, mixed images + videos.

This rule covers the first row.

Failure response

{
  "error": {
    "code": "preflight_failed",
    "rule": "threads.text.required",
    "platform": "threads",
    "message": "Threads text-only posts require non-empty text — pass `media: [...]` for an image/video/carousel.",
    "remediation": "Provide non-whitespace `text`, or include at least one media item."
  }
}

Remediation

Add either non-whitespace text or at least one media item. Threads doesn’t have an “image with no caption” surface that’s also empty-text — there must be either text or media.

threads.text.max_graphemes — 500 graphemes max.
