[Modding]How to summon loot containers with items

[Miyan]

Hi there!

I'm making a mod, but I couldn't make what I want.

What I want to do is that "summon loot containers with items."

To do that, I wrote like below.

    <item name="lootbagSummonerT1">
        <property name="Extends" value="resourceWaterFilter"/>
        <property name="Stacknumber" value="10000"/>
        <property name="EconomicValue" value="0"/>
        <property class="Action1">
            <property name="LootDropEntityClass" value="EntityLootContainerRegular"/>
        </property>
    </item>

But it didn't work and broke my playing game data.

Please help me and tell correct way.

By the way, my goal is to make synthesis of loot bags.

From each loot bags, you will collect tokens.

Merge them and make better loot bags!

I also want opinion about this!
