Conf.Language(14) (copy resource failed: %s)

Error message

Conf.Language(14) (copy resource failed: %s)

What it means

When copying a resource file/folder into the temporary export directory fails, ExportResources wraps the underlying OS error with the localized template Conf.Language(14) ('copy resource failed: %s'). The original error (permissions, missing file, disk full, name collision) is embedded via fmt.Errorf so the log records the source and destination while the user sees a friendly message.

Solutions

1. Read the wrapped %s detail to find the underlying cause (missing file, permission, disk space)
2. Verify the source resource still exists and is readable before exporting
3. Free disk space / check write permissions on the temp export directory
4. Retry after resolving file locks (close apps holding the file, exclude from AV scanning)

Example fix

// before
// source may have been deleted
await exportResources(staleAssetPaths);
// after
const existing = staleAssetPaths.filter(p => fs.existsSync(path.join(workspaceDir, p)));
await exportResources(existing);

for _, p := range paths {
    if _, err := os.Stat(filepath.Join(util.WorkspaceDir, p)); err != nil {
        return fmt.Errorf("resource missing before export: %s", p)
    }
}

_, err := model.ExportResources(paths, name)
if err != nil {
    var msg string
    fmt.Sscanf(err.Error(), Conf.Language(14), &msg) // unwrap %s detail
    log.Printf("export copy failed: %s", msg)
}

When it happens

Trigger: copyExportResource returns an error for any resource in the list — source deleted between listing and copy, read permission denied, destination write failure in TempDir/export, directory walk error, or disk quota exhausted.

Common situations: Asset file removed or renamed after the export list was built; read-only or AV-scanner-locked files on Windows; temp directory on a full disk; exporting a directory containing files the process cannot read.
