Named expression returns an inventory when used with variables

console is full of errors like(they didn't appear in previous version):

[09:33:12] [Server thread/ERROR]: [Skript] '::blocks::146} named "&fDouble Sandstone Slab(All sides)" with lore "&cThis block places as a full block||&cHead is only used for inventory||&ctexture."' is not a valid item data (plotmenu.sk, line 387: player does not have {heads::blocks::146} named "&fDouble Sandstone Slab(All sides)" with lore "&cThis block places as a full block||&cHead is only used for inventory||&ctexture."')

[09:33:13] [Server thread/ERROR]: [Skript] '::mobs::101} named "&fEnder Crystal" with lore "&7You can place ender crystals!"' is not a valid item data (plotmenu.sk, line 426: set slot 3 of player's current inventory to {heads::mobs::101} named "&fEnder Crystal" with lore "&7You can place ender crystals!"')
[09:33:13] [Server thread/ERROR]: [Skript] '::blocks::130} named "&fRedstone Lamp (ON)" with lore "&cThis block places as a full block||&cHead is only used for inventory||&ctexture."' is not a valid item data (plotmenu.sk, line 428: set slot 5 of player's current inventory to {heads::blocks::130} named "&fRedstone Lamp (ON)" with lore "&cThis block places as a full block||&cHead is only used for inventory||&ctexture."')

so looks like it's something to-do with setting heads saved in variables.
I also noticed this happening with other blocks than heads, so might be not only head related

the with lore expression isn't from Skript, could you possibly try without it? Just to confirm it's a Skript issue.

Doesn't give an error for me with PaperSpigot 1.12.2-R0.1-SNP, Skript 2.2-dev34 and SkQuery 3.6.0 using the same code. You may have break something by mistake 😜

[Snow-Pyon]

I'm closing this since it isn't a Skript issue and I can't reproduce it either. Open it again if it happens to be a Skript issue in the end.

here's the problem:
set slot 0 of player's inventory to {item} named "test" = can't understand
set slot 0 of player's inventory to iron ingot named "test" = can understand

variable is the problem, it works if not adding named or with lore.
you maybe tried to re-produce it wrongly

[Nicofisi]

How do you set the {item}

set {item} to player's slot 0

giving/setting the item fully works without adding any "named" things, while it worked fully with named things with variable item in previous version(dev33)

[Blueyescat]

Can reproduce ✔️ Here are the details; it throws the following stacktrace if the variable is set: https://gist.github.com/Blueyescat/deee44d31a874b263241df8a99e90416

The inventory support for Named expression causes the problem, it also doesn't give the error if the variable is set to an inventory.

@Snow-Pyon You did that feature, any idea why/if it might break addons?
