Get all tags of Block

[astral cipher]

Trying to get all the tags from a block in order to add them to another block, but I'm struggling to get it to work. This is my current code (which is kind of jank) along with the errpr it gives me

const $Registry = Java.loadClass("net.minecraft.core.Registry")

ServerEvents.tags('block', event => {
    
    $Registry.BLOCK.getTagNames().map(key => key.location()).forEach(rLoc => {
        
        console.log(rLoc)
        
        if(event.get(rLoc).getObjectIds().contains('minecraft:ice')) {
            console.log('tag contains ice')
            event.add(rLoc, 'ecologics:thin_ice')
            event.add(rLoc, 'immersiveweathering:thin_ice')

        }
    })
})

iirc that's something related to rhino

[astral cipher]

im aware, it's just the error is very unspecific so I'm confused as to what is causing it

[mortal totem]

what the hell

=.=

so um, any ideas on what to do?

[mortal totem]

i would do some debugging to see where it fails, to start with. its way too vague as it is

its the equivalent of "its not working"
which says nothing

[unique vessel]

the stacktrace shows the class of console.log, so it might be one of the two

[mortal totem]

still too vague for my liking

way too vague

[astral cipher]

"not working" in the sense that it throws an error at runtime

ill do a bit more debugging see if i can figure it out

[15:00:39] [ERROR] ! server_scripts:tags.js:5: Error occurred while handling event 'ServerEvents.tags': java.lang.NullPointerException
[15:00:39] [ERROR] ! server_scripts:tags.js:5: java.lang.NullPointerException

this is the least helpful error message ive ever seen

okay something new

const $Registry = Java.loadClass("net.minecraft.core.Registry")

ServerEvents.tags('block', event => {
    
    $Registry.BLOCK.getTagNames().forEach(tag => {
        
        console.log(tag.location())
        
        // if(event.get(rLoc).getObjectIds().contains('minecraft:ice')) {
        //     console.log('tag contains ice')
        //     event.add(rLoc, 'ecologics:thin_ice')
        //     event.add(rLoc, 'immersiveweathering:thin_ice')

        // }
    })
})
