When I access /api/addon/<ID>/files endpoint for certain mods, I'm getting a "500 Internal server error" status, with JSON content telling me pretty much "something went wrong". So far, I was unable to find any connection between the mods in question.
Affected mods (probably incomplete list, just the ones I stumbled upon):
- Just Enough Items (JEI): 238222
- Forestry: 59751
- Ender IO: 64578
- OpenComputers: 223008
