Modding Help Mod Creation - Fatal Exception when all I have is "_metadata"?

I'm trying to create a mod, and what it consistsof currently is a folder, and the file "_metadata".

When I try to launch Starbound I get this error:

https://pastebin.com/raw/nUvu4geQ

This is what is contained in the "_metadata" file:

{
"author" : "SummitMusic"
"description" : "A small mod that adds a powerful sword"
"friendlyName" : "Blade of Chaos"
"name" : "bladeofchaos"
"version" : "1.0"
}

 

You lack commas. should be after every attribute except version because version is last. Commas are separators. Look up JSON syntax because you'll need it.

 

Ah!
Thanks for pointing that out, I wouldn't have thought about that.

I probably should have known this since I work with game configs frequently, but alas.

Thanks for the help!
