System.InvalidOperationException : Operation is not valid due to the current state of the object.

[dreed-sd]

A string format % on a continuation line causes System.InvalidOperationException : Operation is not valid due to the current state of the object.

Minimal GDScript to reproduce:

class_name T
extends RefCounted

func foo() -> void:
    print("hello %s %s"
            % ["world", "!"])
