The uploaded file is empty, lacking any data, which is problematic if contributors are expected to include data. The evidence section would merely confirm the file's emptiness.

Here's an issue based on this:

```json
{
    "issue": "Empty dataset file",
    "evidence": "The uploaded dataset file is empty.",
    "description": "The uploaded dataset file does not contain any data. Contributors are expected to provide actual data in the dataset file."
}
```
