Dear all,

I can't render any document using the following configuration:

```
project:
  title: 'thesis'

format:
  pdf:
    documentclass: thesis
```

The problem seems related to the download of the `.cls` files required. I also tried to download the `classithesis` and `cleanthesis` document class and got the same problem.

I get the following error:

```
