Local File Not Found

**Describe the bug**
Local file storage cannot access one of my datasets.

**To Reproduce**
Steps to reproduce the behavior:
1. Start label-studio:

```bash
LABEL_STUDIO_LOCAL_FILES_SERVING_ENABLED=true LABEL_STUDIO_LOCAL_FILES_DOCUMENT_ROOT=/ label-studio start
```

2. Upload files that specifies the local image get the error:

```bash
[WARNING] Not Found: /data/local-files/
```

and the labeling interface report:

```
There was an issue loading URL from $image value

Things to look out for:

URL is valid
URL scheme matches the service scheme, i.e. https and https
The static server has wide-open CORS, [more on that here](https://labelstud.io/guide/storage.html#Troubleshoot-CORS-and-access-problems)
Technical description:
URL: [/data/local-files/?d=home/USERNAME/data/OpenImages/testv7/0000c64e1253d68f.jpg](http://localhost:8080/data/local-files/?d=home/USERNAME/data/OpenImages/testv7/0000c64e1253d68f.jpg)
```

**I'm quite sure the path is correct and I can access the image. Also, I can access an image of another dataset, e.g., `/data/local-files/?d=home/USERNAME/data/COCO/val2017/xxxx.jpg`**

**Expected behavior**
Successfully loaded the image.

**Screenshots**
If applicable, add screenshots to help explain your problem.


**Environment (please complete the following information):**
- OS: Ubuntu
- Label Studio Version 1.17.0

**Additional context**
I have gone through other issues and found that the local storage support is disappointing. Why not simply read the file given the absolute path?
