BroadcastMessage throws error even using SendMessageOptions.DontRequireReceiver

Unity Engine

Hello
A new day, a new problem.
I send out a BroadcastMessage in this way:

BroadcastMessage(
                "Change",
                changeMessage,
                SendMessageOptions.DontRequireReceiver);

According to the documentation I suggested, “DontRequireReceiver” should suppress exceptions. But as far as I can see in my logs, there are exceptions thrown.
What could be the reason?

Dare I ask what those exceptions are? And are they thrown from the line of code above?

I’m sending out several types of messages. The message itself implements an interface IChangeMessage. The interface itself is derived to e.g. IChangeHeaderMessage.
Eventually inside the script X I have following method:

public void Change(IHeaderChangeMessage message)
{
}

There I receive that message, and is executed as expected.

It is a MissingMethodException.
