OutOfMemoryException: Out of memory

[alessandro-ricci-16]

BUG The linking between the robot i want to control and unity works but when i try to subscribe a topic that had to receive a message of the type "marker array" it send an error of the type OutOfMemoryException.

To reproduce the error I just created a subscriber that receive messages of the type "markerArray". When the robot try to send the messages i got the error.

Console Log Here the console Log:

I need to receive data and update an object with the information ROS2 sent to me. The array contains information about different nodes, I have to retrieve their position and place them in the unity scenario updating their position each time I retrieve different information.

Environment

• Unity Version: Unity 2022.3.10f1
• Unity machine OS + version: Windows 11
• ROS version: ROS 2
