Problem loading timestamps from a Header-only message

[peci1]

Problem description

With ros-noetic-plotjuggler-ros 2.0, I can't load any bag containing http://docs.ros.org/en/noetic/api/cras_msgs/html/msg/Heartbeat.html (install ros-noetic-cras-msgs).

The workaround is to uncheck using embedded timestamps. Or downgrading to ros-noetic-plotjuggler-ros 1.7.0 .

Steps to reproduce (important)

• Ubuntu Focal + ROS Noetic
• Try opening 2024-01-12-13-21-23.zip.
• An error is shown:

The plugin [DataLoad ROS bags] thrown the following exception:
Variant::convert -> cannot convert type16

I tried to debug it, but the parsing seems complex to me. Maybe @facontidavide will have a quicker way to solve it? :)

The error stems from here:

PlotJuggler/plotjuggler_plugins/ParserROS/ros_parser.cpp

Line 108 in 153a9c9

auto nsec = _flat_msg.value[2].second.convert<double>();

Give me a rosbag to reproduce the issue, please

To dowload the latest version RIGHT now, you can use snap:

https://snapcraft.io/plotjuggler-ros

This is the version with "embedded Noetic". The ROS debian packages usually take 2-4 weeks to be updated
