Invalid vanillatweaks JSON throws NullPointerException #163
Description
I was trying to use the vanillatweaks integration for the minecraft docker instance that I am setting up and noticed the example was not working.
I got the following error:
java.lang.NullPointerException: Cannot invoke "me.itzg.helpers.vanillatweaks.model.Type.toString()" because the return value of "me.itzg.helpers.vanillatweaks.model.PackDefinition.getType()" is null
The example was missing the "type" and "result" fields, but it might be better if the file was validated first before trying to use it to prevent confusion and guide users to the problem.
