Hi,

The error is saying that the BUL_create_bulletin signal has two parameters, but you’re emitting it with only one (BulletinConfig.Keys.CraftingMenu). You should then add the missing parameters.

For instance, if a signal is defined as follows:

signal some_signal(a: int, b: int)

You must call it with two fitting parameters, like this:

some_signal.emit(5, 13)

I suppose you should check the class EventSystem where you most likely define all signals. Find the one called BUL_create_bulletin and verify what parameters it expects. Then change the line where you use this signal:

EventSystem.BUL_create_bulletin.emit(BulletinConfig.Keys.CraftingMenu)

to something like

EventSystem.BUL_create_bulletin.emit(BulletinConfig.Keys.CraftingMenu, second_parameter)
