Robot still move although costmap is set to max

[NamTruongTran0]

Hey ROS Community,

i tried to add the nav2_gradient_costmap_plugin but the robot can still move.

The only change i did in gradient_layer.cpp:

  // auto node = node_.lock(); 
  auto node = node_;

I using Ubuntu 20.04 foxy distro.

Thank you so much in advance :)
