}

May be an issue with the json support, or it being atom-beta. but it's still an issue I get on both of my computers running atom-beta with any variation of the json config (Have not tested any other language as I don't prefer any other.)

Am having the same problem. No idea what is going on...

Ooops. Something went wrong.

Seems that in my case it was the beta build that messed it up somehow. Returned to stable atom and it works again.

I like my atom-beta though 🤔

It only seems to occur (on Debian/sid) when I have valid targets. By uninstalling the targets that apply to the project, but keeping ones that don't, the error disappears, replaced by a simple 'no configuration to build this file exists'

I have a PR up for this. I've just been extremely occupied lately. I'll try and get around to merging and releasing this shortly.
