How can I get AnimationNode that is connected to an AnimationNodeOutput

Ah, right. I didn’t test it and the documentation wasn’t clear

It’s possible to get the connections but it’s not exposed directly.

          	} else if (prop_name == "node_connections") {
          		List<NodeConnection> nc;
          		get_node_connections(&nc);
          		Array conns;
          		conns.resize(nc.size() * 3);
          
          		int idx = 0;
          		for (const NodeConnection &E : nc) {
          			conns[idx * 3 + 0] = E.input_node;
          			conns[idx * 3 + 1] = E.input_index;
          			conns[idx * 3 + 2] = E.output_node;
          			idx++;
          		}
          
          		r_ret = conns;
          		return true;
          	}

extends Node


@onready var animation_tree: AnimationTree = $AnimationTree


func _ready() -> void:
	var tree = animation_tree.tree_root as AnimationNodeBlendTree
	var connections = tree.get("node_connections")
	for i in range(0, connections.size(), 3):
		var target = connections[i + 0]
		var input_idx = connections[i + 1]
		var source = connections[i + 2]
		print("Node %s is connected to %s in port %s" % [source, target, input_idx])
