[Bug]: Cannot invoke "java.lang.Float.floatValue()" because the return value of "java.util.Map.get(Object)" is null

1.20.1

What happened?

The game crashed after I ate an apple

The crash log shows that this mod caused the crash

It is also possible that the crash is not caused by mod code, but my datapack configuration problem, please correct

How do you trigger this bug?

The following is the datapack:

1. data\diet\diet\groups\vitamin.json

   {
   "icon": "minecraft:apple",
   "color": "#36ecd5",
   "order": 4,
   "default_value": 0.35,
   "gain_multiplier": 3.0,
   "decay_multiplier": 1.5,
   "beneficial": true
   }

2. data\diet\tags\items\vitamin.json

   {
   "replace":true,
   "values": [
   {
     "id": "minecraft:apple",
     "required": false
   },
   ...
   ]
   }

I thought it was configured correctly.

I used the exclusion method to think about the difference between before and after the datapack modification.

The exception seems to have occurred after I removed the default food group configuration (e.g. fruit.json, vegetables.json) under the tag/items/ directory.

I added them back and no more crashes.

I can play normally now, but I hope this information will help you troubleshoot the problem, or explain why I can't remove the default configuration e.g. fruit.json.
