Editing config file causes weird issues.

[DillPickle66]

I'm working on a vanilla+ modpack and the only things I need to change in the config are "boat": "ONLY_SIMULATION" and
"shaderLightPassthrough": 0.8. So, I removed the other lines in the config like I usually do when making mod packs, but it seems to break upon loading a world. It could be a formatting mistake on my part, but it looks correct to me.
Here's a screenshot of the config https://imgur.com/a/457NQac

{
"effectSpawningRules": {
"boat": "ONLY_SIMULATION"
},
"shaderLightPassthrough": 0.8
}

Expected behavior
It uses the two tweaked settings, and generates the rest of the config like normal. It also shouldn't crash when loading a world.

To Reproduce
Use the config file and load a world.
