Remote debug output errors

[dawnrs]

gd-YAFSM/addons/imjp94.yafsm/scenes/StateMachineEditorLayer.gd

Lines 85 to 99 in 36fe340

	for condition in transition.conditions.values():
	if not ("value" in condition): # Ignore trigger
	continue
	var label = line.vbox.get_node_or_null(NodePath(condition.name))
	tween_labels.tween_property(label, "self_modulate", editor_complementary_color, 0.01)
	tween_labels.tween_property(label, "self_modulate", Color.WHITE, 1)
	else:
	tween_lines.tween_property(line, "self_modulate", Color.WHITE, 0.1)
	# Revert color of TransitionLine condition labels
	for condition in transition.conditions.values():
	if not ("value" in condition): # Ignore trigger
	continue
	var label = line.vbox.get_node_or_null(NodePath(condition.name))
	if label.self_modulate != Color.WHITE:
	tween_labels.tween_property(label, "self_modulate", Color.WHITE, 0.5)

In the line 99， these code sometimes may result this error when I use the remote debug part of this plugin：
res://addons/imjp94.yafsm/scenes/StateMachineEditorLayer.gd:101 - Invalid get index 'self_modulate' (on base: 'null instance').

And there also have some other errors output like:
scene/animation/tween.cpp:103 - Parameter "p_target" is null.

I suppose there are some places in the codes forgetting the null condition.
But the godot editor just print the information from assertion in C++ Code of Tween. So, I cannot find which part of GDScript result it.
I think it must not happen in my script code, because I have not used the tween in my code.

Thanks for any help.

I tried to reproduce the bug with a simple state machine, but it works fine:

remote_debug.mp4

Can you provide a minimal project that can reproduce the bug?
