Could not store Midjourney ${kind} at ${filePath}: ${errorMe

Error message

Could not store Midjourney ${kind} at ${filePath}: ${errorMessage(error)}

What it means

A CommandExecutionError raised when moving the downloaded file into place fails — fs.copyFile from the browser's download location to a temp path, fs.rename to the final filePath, or unlinking the original all throw. The temp file is cleaned up before rethrowing so no partial artifacts remain.

Solutions

Ensure outputDir exists and is writable before the download (the function does mkdir recursive, so check for later deletion or permission changes)
Free disk space if ENOSPC
Check/fix ownership and permissions on outputDir
On Windows, wait for the browser to release the file handle before copying
Inspect errorMessage(error) in the message for the underlying errno (EACCES/ENOENT/ENOSPC) and fix accordingly

Example fix

// before
await downloadRenderedVideo(page, jobId, i, kind, readOnlyDir);
// after
await fs.mkdir(destDir, { recursive: true });
await fs.access(destDir, fs.constants.W_OK);
await downloadRenderedVideo(page, jobId, i, kind, destDir);

Defensive patterns

Strategy: try-catch

Validate before calling

await fs.promises.mkdir(destDir, { recursive: true });
await fs.promises.access(destDir, fs.constants.W_OK);
const free = await checkDiskSpace(path.parse(destDir).root);
if (free.free < 100 * 1024 * 1024) throw new Error('Less than 100MB free — downloads may fail to store');

Try / catch

try {
  await downloadRenderedVideo(page, jobId, i, kind, outDir);
} catch (err) {
  if (err.message.includes('Could not store Midjourney')) {
    if (/ENOSPC/.test(err.message)) console.error('Disk full — free space and retry');
    if (/EACCES|EPERM/.test(err.message)) console.error(`Fix permissions on ${outDir}`);
    if (/ENOENT/.test(err.message)) console.error('Destination removed mid-run — recreate outputDir');
  }
  throw err;
}

Prevention

Create and permission-check outputDir before starting batch downloads
Monitor free disk space for long-running export jobs
Do not delete or move outputDir while the CLI is running
On Windows, ensure no process locks files in the browser download directory

When it happens

Trigger: fs.copyFile or fs.rename in the try block rejects — e.g. destination directory doesn't exist, permissions deny the copy, source vanished mid-copy, or cross-device rename issues (here copy+rename so mainly EACCES/ENOENT/ENOSPC).

Common situations: outputDir was deleted or renamed between creation and storage; read-only or non-writable destination volume; disk full; the browser's temp download was cleaned before the copy; Windows file locking if the browser still holds the file open.
