error running ros2 examples inside Pepper robot

edit

Hello, I compiled ros2 code so when I try to run some examples of ros2 inside the Pepper robot I have the next errors:

Is possible that the problem are the different versions of the repositories? Are some repository version wrong? Is something related with the Fast-RTPS QoS? Any idea about what is happening?

Thanks!
