I am trying to use RTAB-Map ROS with a stereo camera pair simulated in Gazebo. I'm passing --uinfo to the rtabmap node, and the node keeps printing these error messages:

[ERROR] (2020-05-09 12:25:44.055) Memory.cpp:4015::createSignature() Camera calibration not valid, calibrate your camera!
[ERROR] (2020-05-09 12:25:44.055) Memory.cpp:788::update() Failed to create a signature...

I created calibration YAML files for both cameras, and $HOME/.rtabmap/rtabmap.ini contains a reference to the right one, but I still get the errors.
