The command does not evaluate the selector argument "hasitem" -> data.

@Solo alt They both fall under the second issue I stated in my comment. If you don't specify a data value for a Splash Potion, it only looks for Splash Water Bottles (data value 0). You have to you use the correct data value for the effect.

Honestly, I think the three issues I described should be separate bug reports... plus one for the crashing... but all the created ones relating to one of the issues get marked as duplicates of this.

Affects 1.19.10

It works weird in 1.19.41 with maps as well.

Try this:

/give @s empty_map 1 2
/testfor @a[hasitem={item=empty_map}]   <--- No targets matched selector
/testfor @a[hasitem={item=empty_map,data=2}]     <--- Found IzaacB
/give @s filled_map 1 2
/testfor @a[hasitem={item=filled_map}]    <--- No targets matched selector
/testfor @a[hasitem={item=filled_map,data=2}]     <--- No targets matched selector

We want to see if the caller, (@s) has an item in inventory, in this case, lime concrete so the game can do something with it.  

This works with the example given: 

/execute at @s[hasitem= {item=concrete, data=5}] run say lime concrete

this doesn't,

/testfor @s[hasitem= {item=concrete, data=5}]

If the player has lime concrete, the say command runs. If not, it says "no items matched selector

this is how Mojang put the "/testfor" into the @s target using "hasitem={}", as a selector, so it could easily get the data id. testfor only works when the data id = 0.

Accidentally closed this out, apologies.

I suggest expanding the description and title of this report to note in what ways it doesn't work correctly, as it's not one way, as @unknown already pointed out:

• Ignored for block-items.

• all durability-items treated as having data of 0.

• unprovided treated as testing for 0 on items. (Example: no data= in selector for ID potion only finds water bottles, not mundane potions.)

Hopefully this can be fixed soon - there's a ton of ideas I've had that have been limited solely by this issue. I know there's workarounds, but in a good amount of cases, they aren't enough. This should be prioritised.

Workaround (from Discord Server "Bedrock Commands Community"):
To be typed in chat:

/scoreboard objectives add held dummy

Command Line:

/scoreboard players set @a held 0
/scoreboard players set @a [hasitem={item=diamond_sword,location=slot.weapon.mainhand,slot=0}] held 1
/clear @a [scores={held=1}] diamond_sword 69 1

/effect @a [scores={held=1}, hasitem={item=diamond_sword,location=slot.weapon.mainhand,quantity=0}] strength 1 1 true

/replaceitem entity @a [scores={held=1,hasitem={item=diamond_sword,location=slot.weapon.mainhand,slot=0,quantity=0}] slot.weapon.mainhand 0 diamond_sword 1 69

it might work 🙂

@Hangekisobu_231 That workaround only helps for a very small number of cases when you want to detect if the player is holding a non-enchanted item with a data value. It fails to consider enchanted items, items in other hotbar slots, items in the inventory. A fix for the 'hasitem' selector is ESSENTIAL and should be prioritised as it really is impacting community creations. I have personally scrapped 6 or 7 features of maps purely for this reason. I'll give you some examples from the Bedrock Commands Community Discord of how this bug has affected the community:

• Tool repair system which takes into account tool durability (data component), player XP and mending to give the player the exact amount of XP to repair the tool without additional XP

• Crate system which detects if a player has a certain flower (based on crate tiers)

• Removal of banned items including Poison arrows, Locator maps, Invisibility Potions, (Factions Realms)

• Achievement system for detecting when a player has gathered specific items (eg. 64x Spruce Leaves)

• Custom spells system where a player has a particular "Item Totem" (eg. Blue Dye) to perform a specific spell.

• A really awesome in-game market system to sell items on an auction house

These are specific examples that are not possible with that workaround. These examples show unequivocally that this bug is limiting player's creativity and further reinforce the need for this bug to be fixed as soon as possible.

It seems like This only affects blocks and tools because I can get it to work with music discs but not with quartz blocks or swords

I tried to use this command

/execute as @a[hasitem={item=planks,data=0}] run /say has oak planks

but it successfully executes no matter which type of plank you have

still not fully implemented? Lets get on this one... I've tested every potion(drinkable, splash and lingering) as well as every suspicious_stew, ...they work (except for filters in the API noted below).

all of the following FLOWERS resolve to "poppy" (data 0)?

to recreate: copy one of the following 'replaceitem' commands and paste in chat, and then place any 1 tall flower in the players (@s) inventory slot 0. no matter what the flower is, any command listed below will erase it.

// poppy (correct)
"/replaceitem entity @s[hasitem=[{item=red_flower,data=0,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",
//blue orchid <--poppy
"/replaceitem entity @s[hasitem=[{item=red_flower,data=1,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",
// allium <-- poppy
"/replaceitem entity @s[hasitem=[{item=red_flower,data=2,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",
// azure_bluet aka houstonia <-- poppy
"/replaceitem entity @s[hasitem=[{item=red_flower,data=3,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",
// red tulip <-- poppy
"/replaceitem entity @s[hasitem=[{item=red_flower,data=4,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",
// orange tulip <-- poppy
"/replaceitem entity @s[hasitem=[{item=red_flower,data=5,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",
// white tulip <-- poppy
"/replaceitem entity @s[hasitem=[{item=red_flower,data=6,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",
// pink tulip <-- poppy
"/replaceitem entity @s[hasitem=[{item=red_flower,data=7,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",
// oxeye daisy aka oxeye <--poppy
"/replaceitem entity @s[hasitem=[{item=red_flower,data=8,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",
// cornflower <-- poppy
"/replaceitem entity @s[hasitem=[{item=red_flower,data=9,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",
// lily of the valley <-- poppy
"/replaceitem entity @s[hasitem=[{item=red_flower,data=10,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1"
// poppy (correct I guess)
"/replaceitem entity @s[hasitem=[{item=red_flower,data=11,quantity=1,location=slot.inventory,slot=0}]] slot.inventory 0 destroy air 1",

there is currently no way to use either a command (shown above) or a filter (shown below) in add-on entity to identify alt states of items, or at least it isn't in any documentation publicly available.

UPDATE 6/1/24: there is a filters only solution I found, based on that all minecraft namespace items do not need the 'minecraft:' namespace
