    Error initializing tree action

    I've just recently updated a site to UMv7.6.3 and was looking at the log file when I came across the following error;

    [52] ERROR Umbraco.Web.Trees.LegacyTreeJavascript - Error initializing 
    tree action System.NullReferenceException: Object reference not set to an 
    instance of an object. at 
    umbraco.BusinessLogic.Actions.Action.ValidateActionJs(IAction action) at 

    Could anyone point me in the right direction on how to fix this and why this happens? Thanks!
