Hi,

Do all images are null? you can add a check like this:

if(!srv.response.data.nodes[i].image.empty())
   // convert image
else
   ROS_WARN("Node %d doesn't have image set", i);

Afterwards, if some are null, it may be because of some parameters on the rtabmap side that make it not keep some images.
