I'm trying to add a Custom Infusion Recipe using a Thaumcraft Essentia Phial as ingredient, but It didn't work.

Here is my json:

Result:

I tried it too:
"thaumcraft:phial,1,1,{Aspects:[0:{amount:10,key:"desiderium"}]}"
and:
"thaumcraft:phial,1,1,{Aspects: [{amount: 10, key: "desiderium"}]}"

but...

All quotes within the string need to be escaped with backslash.
e.g
this "thaumcraft:phial,1,1,{Aspects:[0:{amount:10,key:"desiderium"}]}"
Should be this: "thaumcraft:phial,1,1,{Aspects:[0:{amount:10,key:\"desiderium\"}]}"

Same problem. JSON:

Result:

Phial /ct hand:

Ok with the correct item in your hand run this command and show me the output
/bcore_util nbt

Sorry i didn't get back to you. The correct tag is as follows.
"thaumcraft:phial,1,1,{Aspects:[{amount:10,key:\"desiderium\"}]}"

Oh sorry, I forgot to answer. Everything works fine using thaumcraft:phial,1,1,{Aspects:[{amount:10,key:\"desiderium\"}]}
But it means /bcore_util nbt is giving the wrong nbt for this item.

Thanks for helping-me! :)

Good to know. Was wondering if this worked myself, though I have yet to try.
