error: field 'platform' has incomplete type

Issue template

• Hardware description: STM32F722ZET6U
• RTOS: FreeRTOS
• Installation type: custom ROS message
• Version or commit hash: Humble

Steps to reproduce the issue

I'm a beginner doing tutorials on the "micro.ros.org " site.
Among them, an error occurs during the "How to include a custom ROS message in micro-ROS" process and asks questions.
An error occurs while building micro-ROS workspace, and it does not work.
I'd appreciate your help.

Actual behavior

The error contents are as follows.

firmware/mcu_ws/eProsima/Micro-XRCE-DDS-Client/include/uxr/client/profile/transport/serial/serial_transport.h:39:30: error: field 'platform' has incomplete type
struct uxrSerialPlatform platform;
^~~~~~~~

Additional information

I attach the details as a picture.

Commencez par firmware/mcu_ws/eProsima/Micro-XRCE-DDS-Client/include/uxr/client/profile/transport/serial/serial_transport.h et examinez la sortie de compilation ainsi que les captures d’écran jointes pour trouver la définition manquante de uxrSerialPlatform. Reproduisez le tutoriel sur les messages ROS personnalisés sur le STM32F722ZET6U avec FreeRTOS, puis identifiez le problème de configuration ou d’include qui provoque l’erreur de type incomplet. Le travail est terminé lorsque le workspace micro-ROS se construit avec succès.
