ROS2 foxy ros1_bridge

edit

I want to use ROS2 Foxy to spawn a Turtlebot in Gazebo which is in ROS1.

Inside ROS1 when I do rosservice list, I see the following

/gazebo/apply_body_wrench
/gazebo/apply_joint_effort
/gazebo/clear_body_wrenches
/gazebo/clear_joint_forces
/gazebo/delete_light
/gazebo/delete_model
/gazebo/get_joint_properties
/gazebo/get_light_properties
/gazebo/get_link_properties
/gazebo/get_link_state
/gazebo/get_loggers
/gazebo/get_model_properties
/gazebo/get_model_state
/gazebo/get_physics_properties
/gazebo/get_world_properties
/gazebo/pause_physics
/gazebo/reset_simulation
/gazebo/reset_world
/gazebo/set_joint_properties
/gazebo/set_light_properties
/gazebo/set_link_properties
/gazebo/set_link_state
/gazebo/set_logger_level
/gazebo/set_model_configuration
/gazebo/set_model_state
/gazebo/set_parameters
/gazebo/set_physics_properties
/gazebo/spawn_sdf_model
/gazebo/spawn_urdf_model
/gazebo/unpause_physics
/gazebo_gui/get_loggers
/gazebo_gui/set_logger_level
/gazebo_gui/set_parameters
/master_discovery/get_loggers
/master_discovery/list_masters
/master_discovery/refresh
/master_discovery/set_logger_level
/master_sync/get_loggers
/master_sync/get_sync_info
/master_sync/set_logger_level
/param_sync/get_loggers
/param_sync/set_logger_level
/rosout/get_loggers
/rosout/set_logger_level

However when I run ros2 run ros1_bridge dynamic_bridge --bridge-all-topics I see the following

Created 2 to 1 bridge for service /gazebo/pause_physics
Created 2 to 1 bridge for service /gazebo/reset_simulation
Created 2 to 1 bridge for service /gazebo/reset_world

Created 2 to 1 bridge for service /master_discovery/refresh

^C[MrTurtle] root@turtlebot_0:~/ws/src/robotic_order_fulfillment_robotic_turtle/scripts$ removed 1to2 bridge for topic '/rosout'

Which consequently leads to the following (after sourcing setup.bash)

$ ros2 service list
/gazebo/pause_physics
/gazebo/reset_simulation
/gazebo/reset_world
/gazebo/unpause_physics
/master_discovery/refresh
/ros_bridge/describe_parameters
/ros_bridge/get_parameter_types
/ros_bridge/get_parameters
/ros_bridge/list_parameters
/ros_bridge/set_parameters
/ros_bridge/set_parameters_atomically

As you can see, not all services are available in ROS2. However, when I try to access the services that are availeble (e.g. /gazebo/pause_physics ) it does what is expected from it.

What should I do to see all the services available in ROS1?
