Getting error on initalizing webviz

I think that may be it…

We use the rosbag C++ API directly.

https://github.com/ros/ros_comm/tree/melodic-devel/tools/rosbag

Specifically https://github.com/ros/ros_comm/blob/melodic-devel/tools/rosbag_storage/include/rosbag/bag.h#L165 that line is what it comes down to.

I think I’ll check the changes that fix is doing and either make an upstream change to rosbag or change our downstream use of it. Thanks for the help.
