can't build firmware after putting custom message

[AhmadSameh]

Issue template

• Hardware description: esp32
• RTOS: FreeRTOS
• Installation type: micro_ros_setup,
• Version or commit hash: humble

Steps to reproduce the issue

1- followed the custom message tutorial on the micro-ros documentation
2- built the package using the command
ros2 run micro_ros_setup build_firmware.sh

Expected behavior

should compile just fine

Actual behavior

this error shows up:

Crosscompiled environment: cleaning path

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

Does it works without using custom messages?

In anyn case, the recommended option for using ESP32 is using micro-ROS component for ESP-IDF

@pablogs9 when I wrote this problem I had expected that on a successful building, I would have a header file and then I would add it to the Arduino Library, but that doesn't seem to be the case.
So I apologize for the sudden change of questions, but how can I add a custom message to the micro-ros Arduino library.

If you use the mentioned component, just add your packages here: https://github.com/micro-ROS/micro_ros_espidf_component/tree/iron/extra_packages
