Error at oxide.reload - file modifications

Please help.    I'm getting an error after modifying the files. I've done this before, and it worked flawlessly, so I'm probably just doing something really stupid.

it starts up fine, and generates the default.json and customLoot.jsn files properly. i've modified the files using find/replace, so there shouldn't be any syntax errors, and I've run it through a json checker.  but it seems that no matter what i modify, I'm getting the attached server error, and the following error in my log when i run oxide.reload CustomLoot:

CustomLoot.cs - i haven't touched.

Thanks, Steenamaro!

I changed the top 4 items to true. I changed the Category probabilites  and allowBlueprints manually. I changed the Spawn_Vanilla_Scrap: false, and multiplier. I've just used a find/replace for the "probability": 7, under LootTypes - so they should all be the same.  So just those 4 changes.

default.json

i think i've figured it. in my old files, there was no line: "Vanilla_Scrap_Multiplier": INTEGER. i've changed it to a decimal. i'm going to try it again by leaving it at 1 and changing the scrap output manually in each container.

Yes! That was it. Can not lower the Multiplier by decimal places.
