Unable to delete nodes in Project map when using Godot 3.5.rc5 about project-map

[Yogoda]

Thank you for the nice report and fix :)

I committed the fix on Github.

It appears the issue is that in godot 3.5 they changed the delete_nodes_request signal to take an array of nodes.

To fix this I just needed to add an input variable.
On line 219 of project_map.gd "func _on_GraphEdit_delete_nodes_request(array = Array()):"
After this deleting works just fine after saving, closing and reopening godot 3.5.rc5.

Edit:
Tested this change in both 3.5.rc5 and 3.4.4. Seems to work fine in both versions.
