Stereo interface received non-stereo frame, exiting stereo

[planch98]

Hi, I'm working with the stereo cameras. The stereo images and the disparity image are shown on voxl-portal. After launching voxl-mpa-to-ros and subscribing to /stereo_disparity/left with rostopic echo, voxl-mpa-to-ros prompt this error:

Stereo interface received non-stereo frame, exiting stereo

After that, the topics related to stereo interface (/stereo_disparity/left,/stereo_disparity/right) disappear. Same happens with /stereo_disparity_scaled/right

I also tried to visualize the disparity on rviz. In that case the mpa-to-ros crashes with the following:

[voxl_mpa_to_ros_node-2] process has died [pid 5846, exit code -11, cmd /opt/ros/melodic/lib/voxl_mpa_to_ros/voxl_mpa_to_ros_node __name:=voxl_mpa_to_ros_node __log:=/home/root/.ros/log/2bfc2770-2715-11ee-9d49-00c0cab15bca/voxl_mpa_to_ros_node-2.log].
log file: /home/root/.ros/log/2bfc2770-2715-11ee-9d49-00c0cab15bca/voxl_mpa_to_ros_node-2*.log

Any clue on what is going on?
