${label} exceeds Midjourney's 10MB upload limit: ${ref.value

Error message

${label} exceeds Midjourney's 10MB upload limit: ${ref.value}

What it means

Midjourney's upload endpoint accepts images up to 10MB (MAX_REFERENCE_BYTES). When a local reference's stat size exceeds this constant, the library throws this ArgumentError before starting the browser upload, avoiding a guaranteed-to-fail transfer.

Solutions

1. Resize/compress the image below 10MB (e.g. magick input.png -resize 2048x -quality 85 output.webp)
2. Re-export as JPEG/WEBP at lower quality
3. Crop or downscale before passing to the CLI

Example fix

// before
clis/midjourney --refs ./4k-render.png   // 18MB
// after
magick ./4k-render.png -resize 2048x2048 -quality 85 ./render.webp
clis/midjourney --refs ./render.webp

const MAX = 10 * 1024 * 1024;
const s = await fs.stat(p);
if (s.size > MAX) await compressImage(p); // e.g. magick p -resize 2048x -quality 85 out.webp

const withinUploadLimit = async (p, max = 10 * 1024 * 1024) => (await fs.stat(p)).size <= max;

try {
  await validateLocalReferences(refs, 'refs');
} catch (e) {
  if (String(e.message).includes("10MB upload limit")) {
    console.error('Compress/resize the image below 10MB:', e.message);
  }
  throw e;
}

When it happens

Trigger: A local PNG/JPEG/WEBP/GIF whose byte size exceeds 10MB — full-resolution exports, high-DPI screenshots, raw scans, or long animated GIFs.

Common situations: Designers exporting 4K renders, lossless screen recordings saved as GIF, camera originals, or datasets with source-resolution imagery.
