I get this set of errors printed out in the console when I open my project:
ERROR: Cannot get path of node as it is not in a scene tree.
At: scene/main/node.cpp:1642
ERROR: (Node not found: "" (relative to "").)
At: scene/main/node.cpp:1371
ERROR: ViewportTexture: Path to node is invalid.

And similar is printed out again when I run the project. I'd like to eliminate them but there's no info that points to their exact origin. I manually checked suspicious places but couldn't find anything problematic. How do we deal with this?
