如何删除旧图像并将其替换为另一个我的谷歌存储驱动器

Question

我想在我的应用程序上编辑一个表单，并更新包括图像在内的所有其他数据，但我发现旧图像并没有从谷歌驱动器文件夹中删除，而是添加了新图像。请问我在这段代码中做错了什么？

// Check if a new image was uploaded
    if ($this->image) {
        // Delete the old image from Google Drive
        $oldImagePath = $this->grade->image;
        Storage::disk('google')->delete($oldImagePath);

        // Store the new image in Google Drive
        $newImagePath = $this->image->store('/', 'google');

        // Update the image and image URL in the validated data
        $validatedData['image'] = $newImagePath;
        $validatedData['image_url'] = Storage::disk('google')->url($newImagePath);
    }
