visualize! is ambiguous in example notebook

[janbruedigam]

Running the cartpole example notebook, I get the following error when calling

visualize!(vis, model, TrajectoryOptimization.get_trajectory(altro))

ERROR: LoadError: MethodError: visualize!(::Visualizer, ::Cartpole{Float64}, ::Traj{4,1,Float64,RobotDynamics.GeneralKnotPoint{Float64,4,1,SArray{Tuple{5},Float64,1,5}}}) is ambiguous. Candidates:
  visualize!(vis, model::AbstractModel, Z::RobotDynamics.AbstractTrajectory) in TrajOptPlots at C:\Users\janbr\.julia\packages\TrajOptPlots\VirKW\src\rigid_bodies.jl:32
  visualize!(vis, model::Cartpole, x::AbstractArray{T,1} where T) in TrajOptPlots at C:\Users\janbr\.julia\packages\TrajOptPlots\VirKW\src\models.jl:43
  visualize!(vis, model::AbstractModel, Zs::RobotDynamics.AbstractTrajectory...) in TrajOptPlots at C:\Users\janbr\.julia\packages\TrajOptPlots\VirKW\src\rigid_bodies.jl:42
Possible fix, define
  visualize!(::Any, ::Cartpole, ::RobotDynamics.AbstractTrajectory)
