How do I track/see the errors/bugs thrown by the Blender plugin?

You can view/track any errors that the plugin may have encountered while importing and setting up your assets right inside Blender.

In order to do this, go to Window>Toggle System Console in Blender, then re-export the asset from Bridge. You should now be able to see the plugin's log in Blender. This log contains all the information including any errors encountered by the plugin while importing and setting up your assets.
