Conf.Language(14) (copy data dir failed: %s)

Error message

Conf.Language(14) (copy data dir failed: %s)

What it means

exportData (called by ExportData) copies the workspace data directory via filelock.Copy; if that copy fails, it wraps the OS error with Conf.Language(14) ('Export failed: %s'). The inner err.Error() carries the underlying reason (permission, file-in-use, IO error).

Solutions

1. Read the wrapped %s detail to identify the failing file/reason and fix that specific cause
2. Check write permissions and free space on the export destination
3. Close other processes holding workspace files (sync clients, editors, antivirus) and retry

Example fix

// before
util.ExportData() // -> Export failed: ... access is denied
// after
chmod/write-enable destination dir, close file locks, then util.ExportData()

const targetOk = await canWrite(exportFolder);
const freeOk = (await getDiskUsage(exportFolder)).free > 0;
if (!targetOk || !freeOk) throw new Error("Export destination is not writable");

try {
  await exportData();
} catch (e) {
  // Conf.Language(14) wraps the OS error in e.msg after 'Export failed: '
  const inner = String(e.msg).split(": ").slice(1).join(": ");
  logDetailed(inner); // e.g. ENOSPC / EACCES / file-in-use
}

When it happens

Trigger: filelock.Copy(workspace/data, exportFolder) fails during export-data — any OS-level copy error while duplicating the data dir.

Common situations: Destination volume full or write-protected; file locked by another process (Windows AV/indexer); permission denied on target folder; source file deleted mid-copy by sync.
