robot-log-visualizer crashes whe `yarp-robot-name` field is empty #34

Closed Nicogene closed 2 years ago

Nicogene commented 2 years ago

In my .mat file I have:

robot_logger_device = 

  struct with fields:

    description_list: {26×1 cell}
     yarp_robot_name: [1×0 char]
        joints_state: [1×1 struct]

>> robot_logger_device.yarp_robot_name

ans =

  1×0 empty char array

And when I try to load it with robot-log-visualizer I get:

[2758:2825:0406/161520.657265:ERROR:context_group.cc(181)] ContextResult::kFatalFailure: ES3 is blacklisted/disabled/unsupported by driver.
