After updating forms to 4.23.3, my website throws the following exception during routeCollection.MapMvcAttributeRoutes():
System.ArgumentException: 'Cannot call action method 'Void GetFormExternalResources(System.Collections.Generic.List`1[System.String] ByRef, System.Collections.Generic.List`1[System.String] ByRef)' on controller 'EPiServer.Forms.Controllers.FormContainerBlockController' because the parameter 'System.Collections.Generic.List`1[System.String]& scripts' is passed by reference.
Parameter name: methodInfo'
Has anyone else encountered this, how to resolve the issue?
