Custom animation node not working in standalone

Ok, I solved it.

This was my .uproject module configuration:



"Modules": 
	{
		"Name": "MyGame",
		"Type": "Runtime",
		"LoadingPhase": "Default",
		"AdditionalDependencies": 
			"Engine",
			"CoreUObject"
		]
	},
	{
            "Name": "MyGameEditorExtension",
            "Type": "Editor",
            "LoadingPhase":  "PostEngineInit"
        }
	]


I have edited the type and the loading phase of my editor extension module:



"Modules": 
	{
		"Name": "MyGame",
		"Type": "Runtime",
		"LoadingPhase": "Default",
		"AdditionalDependencies": 
			"Engine",
			"CoreUObject"
		]
	},
	{
            "Name": "MyGameEditorExtension",
            "Type": "Runtime",
            "LoadingPhase":  "Default"
        }
	]
