Could not locate Midjourney ${slotLabel} slot after upload

Error message

Could not locate Midjourney ${slotLabel} slot after upload

What it means

Thrown when markReferenceTarget cannot find the target drop area (slot) for the given slotLabel after uploading a reference image. The in-page evaluate returns {ok:false, source:true, target:false} because no matching slot element was located in the Midjourney composer.

Solutions

1. Ensure openImagePanel(page) ran and the image panel is visible before marking slots.
2. Log/dump the slot DOM to verify the current slot label text and update slotLabel mapping.
3. Add a wait/retry before evaluate so the slot element has rendered.
4. Reload the Midjourney page and open a fresh composer.

Example fix

// before
await markReferenceTarget(page, url, label);
// after
await openImagePanel(page);
await page.wait(1);
await markReferenceTarget(page, url, label);

const hasSlot = await page.evaluate((label) =>
  [...document.querySelectorAll('div,span')].some(n => n.textContent?.trim() === label), slotLabel);
if (!hasSlot) await openImagePanel(page);

try {
  await markReferenceTarget(page, url, label);
} catch (err) {
  if (String(err.message).includes('Could not locate')) {
    await openImagePanel(page);
    await markReferenceTarget(page, url, label);
  } else throw err;
}

When it happens

Trigger: Calling uploadReferencesToSlot / markReferenceTarget when the reference slot panel is closed, the slot label changed, or the panel DOM has not rendered yet.

Common situations: Image panel not opened before marking; Midjourney renamed slot labels (e.g. 'Style References'); slow rendering so slots are absent; page in a different state (no draft open).
