Error in RosFaceDetector

[vignif]

Hi! thank you so much for your efforts in ros4hri.

I have a camera attached to my machine and I'm trying to detect faces as described in your docs.
The default roslaunch hri_face_detect detect.launch works greatly.
However, when the face_mesh parameter is set to False this error appears:

[ERROR] [1664892161.286484]: bad callback: <bound method RosFaceDetector.callback of <__main__.RosFaceDetector object at 0x7f3071b03f70>>
Traceback (most recent call last):

y: 0
c: 1, .....

My launch file looks like this:

<launch>
   <include file="$(find realsense2_camera)/launch/rs_camera.launch">
        <arg name="device_type" value="d435"/>
    </include>
    <include file="$(find hri_face_detect)/launch/detect.launch">
      <arg name="face_mesh" value="False"/>
    </include>
</launch>

Do you have any suggestions?
Thank you so much!
