“Cannot call method ‘is_node_ready’ on a null value."

Posting here so to be linked for later use instead of re-typing this every time

Make sure you paste scripts instead of screenshots. To properly format pasted code use three ticks ``` at the start and end of your paste like so:

# type or paste code here
func _ready() -> void:
print("My ready function!")

Results in:

# type or paste code here
func _ready() -> void:
    print("My ready function!")

Press the </> button or ctrl+e in the forum to create these ticks.

Can you show your CardState-script?
