Error while reading params file

[vimalrajayyappan]

Following are the parameters I'm using for TEB Local Planner [ROS2 , Foxy version]

• While using circular footprint model there were no issues.
  the params are:

       plugin: "teb_local_planner::TebLocalPlannerROS"
        footprint_model.type: circular
        footprint_model.radius: 2.3
  

• But when I switch to polygon model I got error as :
  what(): failed to initialize rcl: Couldn't parse params file:

The params I'm using are

  plugin: "teb_local_planner::TebLocalPlannerROS"
  footprint_model.type: polygon  
  footprint_model.vertices: [[-0.27, 0.315], [0.27, 0.315], [0.27, -0.315], [-0.27, -0.315]]
  min_obstacle_dist: 0.5
  inflation_dist: 1.0 #0.1
  # costmap_converter_plugin: "costmap_converter::CostmapToPolygonsDBSMCCH"

  min_turning_radius: 3.0
  transform_tolerance: 0.2

  xy_goal_tolerance: 0.1

Looking for help. Thanks in advance! :)

Hi team, Please have a look and kindly provide your valuable advise.

  footprint_model:
    type: "polygon"
    vertices: "[[-0.27, 0.315], [0.27, 0.315], [0.27, -0.315], [-0.27, -0.315]]"
