ROS2 cartographer unable to see map (.pbstream) in rviz2 #1841

I'm using ros2 cartographer for localisation purpose. Below are following things that i have done until now.

I have mapping using slam tool box.
ros2 service call /write_state cartographer_ros_msgs/srv/WriteState "{filename: 'map_nv25_v1.pdstream',include_unfinished_submaps : false}" (I have used this code to save the map as .pbstream)
For some strange reason when i try to save .pbstream (map) while running gazebo simulation and upload it during localisation,I can see the map in rviz2 but when i do the same process using real robot i cant find map in rviz2.

below is my cartographer configuration
ROBOT.lua

include "map_builder.lua"
