BlockBench modded Entites Models error 1.17+

[Legogic]

public class MaypoleTest2<T extends Entity> extends EntityModel<T> {
    // This layer location should be baked with EntityRendererProvider.Context in the entity renderer and passed into this model's constructor
    public static final ModelLayerLocation LAYER_LOCATION = new ModelLayerLocation(new ResourceLocation("modid", "maypoletest2"), "main");
    private final ModelPart bb_main;

    public MaypoleTest2(ModelPart root) {
        this.bb_main = root.getChild("bb_main");
    }

    public static LayerDefinition createBodyLayer() {
        MeshDefinition meshdefinition = new MeshDefinition();
        PartDefinition partdefinition = meshdefinition.getRoot();

        PartDefinition bb_main = partdefinition.addOrReplaceChild("bb_main", CubeListBuilder.create().texOffs(0, 0).addBox(-1.0F, -2.0F, -1.0F, 2.0F, 2.0F, 2.0F, new CubeDeformation(0.0F)), PartPose.offset(0.0F, 24.0F, 0.0F));

        return LayerDefinition.create(meshdefinition, 164, 164);
    }

    @Override
    public void setupAnim(T entity, float limbSwing, float limbSwingAmount, float ageInTicks, float netHeadYaw, float headPitch) {

    }

    @Override
    public void renderToBuffer(PoseStack poseStack, VertexConsumer vertexConsumer, int packedLight, int packedOverlay, float red, float green, float blue, float alpha) {
        bb_main.render(poseStack, vertexConsumer, packedLight, packedOverlay, red, green, blue, alpha);
    }
}

(just the start of the java file code ,Also its litteraly just a block 1,1,1 model same thing happened with an empty or full model)

This error keeps popping WITH anything thats a 1.17+ model 

Tried and THE EXACT SAME MODEL in 1.13-1.15 and and it works 

I need It in 1.19(1.17+) so 1.13 models working is worthless

i dont really understand this type of code so i dont know how to fix it or what it means
