FastDDS Visualizer Compatibility with FastDDS V2.13.2 and FastCDR V2.1.3

[bshantam97]

I am trying to visualize data using the fastdds viz pluging. My publisher is ustilizing FastRTPS V2.13.2 and FastCDR v2.1.3. Whenever I try to plot the data/discover on domain the application goes into a segmentation fault. Is this a version compatibility issue ?

I have faced the same kind of issue,

After a few research found these:

• Fast-DDS-monitor crash with certain idl types [15446] Fast-DDS#2926
• [15446] TypeObject for sequences/arrays/maps of nested types crashes Fast-DDS#3296

When I experienced the crash I used sequence in my Idls, once I switched to "keyed" topics no more crashes.
