How do read data from the app loader

I tried to follow the tutorial here: http://www.espruino.com/Bangle.js+Storag­e but get no content for any file.

I'm trying to read a json file from the app loader, but I always get 0 bytes. Maybe someone has a clue what I'm doing wrong, steps to reproduce:

1. Running a local server with npm start
   
2. Add a interface.html to any random app by adding
   "interface": "interface.html"
   to metadata.json
   
3. Create interface.html with content from http://www.espruino.com/Bangle.js+Storag­e
   
4. Replace 'gpspoilog.csv' with 'setting.json' because that file surely exists. But with the download button I get no data. Output in the console:
   
   

readStorageFile "setting.json"
comms.js:431 readTextBlock read started...
comms.js:417 size is 0
