Topic Not Visible error

Start by reproducing the documented micro_ros_setup create, build, flash, and agent commands for the ESP32 with serial transport. Compare the micro-ROS Agent output with ros2 topic echo /microROS/ping and the reported expected messages; done means the ping topic is discoverable and publishes the expected messages.

Issue template

• Hardware description: ESP32-WROVER-E
• RTOS: ROS2 Humble
• Installation type: micro_ros_setup
• Version or commit hash: Ubuntu 22.04.3 LTS, Arduino 1.8.19

Steps to reproduce the issue

Source the ROS 2 installation

source /opt/ros/$ROS_DISTRO/setup.bash

Create a workspace and download the micro-ROS tools

mkdir microros_ws
cd microros_ws
git clone -b $ROS_DISTRO https://github.com/micro-ROS/micro_ros_setup.git src/micro_ros_setup

Update dependencies using rosdep

sudo apt update && rosdep update
rosdep install --from-paths src --ignore-src -y

Install pip

sudo apt-get install python3-pip

Build micro-ROS tools and source them

colcon build
source install/local_setup.bash

Create step

ros2 run micro_ros_setup create_firmware_ws.sh freertos esp32

Configure step with ping_pong app and serial transport

ros2 run micro_ros_setup configure_firmware.sh ping_pong --transport serial

I followed all these steps no issues till now

Build step

ros2 run micro_ros_setup build_firmware.sh

when i executed command in between it shows as "colcon build stderr output"
later it will complete the execution without any error 100% build target app.

Flash step

ros2 run micro_ros_setup flash_firmware.sh

Download micro-ROS-Agent packages

ros2 run micro_ros_setup create_agent_ws.sh

Build step

ros2 run micro_ros_setup build_agent.sh

while executing this line it gives

$ ros2 run micro_ros_setup build_agent.sh
source install/local_setup.bash

Run a micro-ROS agent

$ ros2 run micro_ros_agent micro_ros_agent serial --dev /dev/serial/by-id/usb-Silicon_Labs_CP2102N_USB_to_UART_Bridge_Controller_8484ebb7cd24ec11ad45dd31b659684c-if00-port0
executes correctly

In another terminal if i run
source /opt/ros/$ROS_DISTRO/setup.bash

Subscribe to micro-ROS ping topic

ros2 topic echo /microROS/ping

ros2 topic echo /microROS/ping
WARNING: topic [/microROS/ping] does not appear to be published yet
Could not determine the type for the passed topic

I have gone through Domail ID and set it to even 0 then also i am getting the same result.
I even refered this and other links regarding the same https://github.com/micro-ROS/micro_ros_arduino/issues/21

This line also gets exicuited correctly code gets uploaded to the board.

Expected behavior

You should see the topic messages published by the Ping Pong node every 5 seconds:

user@user:~$ ros2 topic echo /microROS/ping
stamp:
sec: 20
nanosec: 867000000
frame_id: '1344887256_1085377743'

stamp:

nanosec: 942000000
frame_id: '730417256_1085377743'
ros2 run micro_ros_setup create_firmware_ws.sh freertos esp32

Actual behavior
