Error while loading particle effect

[4lfg24]

I'm trying to load a .efk file like this:

    //effekseer stuff
    lateinit var assetManager:AssetManager
    lateinit var myFileHandleResolver: FileHandleResolver
    lateinit var manager:EffekseerManager
    lateinit var myParticle:EffekseerParticle

    init {
        EffekseerGdx.init()
        initEffekseer()
        initializeBullet()
        createAxes()
        createFloor(50f, 1f, 50f)
    }


    private fun initEffekseer() {

        myFileHandleResolver=MyFileHandleResolver()
        assetManager= AssetManager(myFileHandleResolver)
        assetManager.setLoader(EffekseerParticleSubAssetLoader.Result::class.java,
            null,EffekseerParticleSubAssetLoader(myFileHandleResolver))

        assetManager.setLoader(
            EffekseerParticleAssetLoader.Result::class.java, null, EffekseerParticleAssetLoader(myFileHandleResolver)
        )
        manager= EffekseerManager(camera, EffekseerCore.TypeOpenGL.OPEN_GL2,1000,modelBatch.renderContext)

        myParticle= EffekseerParticle(manager)
        myParticle.setMagnification(20f)

        myParticle.syncLoad(assetManager, "random colors.efk")

        myParticle.play()
    }

    override fun render(delta: Float) {
        super.render(delta)

        manager.draw(delta)

        manager.drawAfterUpdate()

        dynamicsWorld?.stepSimulation(delta)
        debugDrawer?.begin(camera)
        dynamicsWorld?.debugDrawWorld()
        
        debugDrawer?.end()
    }

    class MyFileHandleResolver:FileHandleResolver{
        override fun resolve(fileName: String?): FileHandle {
            return Gdx.files.internal(fileName)
        }

    }

    override fun dispose() {
        super.dispose()
        myParticle.dispose()
        manager.dispose()
    }
}

The super.render method is:

fun render(delta:Float){
cameraController.update()
        ScreenUtils.clear(Color.BLACK, true)
        shadowLight!!.begin(Vector3.Zero, camera.direction)
        shadowBatch.begin(shadowLight!!.camera)
        shadowBatch.render(renderInstances)
        shadowBatch.end()
        shadowLight!!.end()
        modelBatch.begin(camera)
        modelBatch.render(renderInstances, environment)
        modelBatch.end()

        //setting up the debug renderer

        stage.act()
        stage.draw()
}

I'm using version 2.2.3 of effekseer for libgdx, I tried to load the .efk file asyncronously via myParticle.asyncload but the onEffectLoaded method wouldn't execute (I set it to println "particle loaded" when finished loading, but it just doesn't do it), in the log it says:

Also If you could link a project that uses effekseer-gdx as an exaple it would be really useful, thanks.
