Error 500 when calling API

Describe the bug Good morning, I just discovered your version of STUdio (STUdio v0.5.2) and it is much faster than the original :)

On the other hand, I developed a small FRONT tool in Angular to allow me to manage my packs more quickly (mass sending and deletion) and I encountered a problem with your version.

Indeed, when I call certain endpoints, they return me a 500 error.

Note that the embedded front with STUdio works very well. On the other hand, the API call does not crash in version 0.3.1 of STUdio (of Marian).

To Reproduce Here, the code I use to perform actions :

public pushStory(_uuid: string, _path: string) {
        return this.http.post<any>("http://localhost:8080/api/device/addFromLibrary", 
            JSON.stringify({uuid: _uuid, path: _path})
        );
    }

Expected behavior Correct response of API
