matriax Target camera does not have an ellipsoid. Each camera has its own parameters.
And how can we know that? In the description camera will be great some advices like that, or simply make Babylon not take in consideration the ellipsoid when Target Camera is added to avoid the error.
BTW, the TargetCamera was for fix the FreeCamera problem when you fly, but with target camera seems we have to build our own controls for movement and camera rotation(for mouse). And also, without ellipsoid how the camera check the collisions? Also the gravity not works with targetCamera...
So, in my opinion better find a solution/fix for the FreeCamera to avoid fly, instead of build from 0 all the behaviour in Target Camera.
Any ideas?, Maybe by code in the plugin some action in the camera to switch if the FreeCamera take or not the Y.rotation in consideration? So if deactivated you walk etc... and with that active you can fly or use it as a "JetPack behaviour".
Other thing i'm wondering is, will be possible add in the plugin some action to use native Babylon.js code? So i can ask in the Babylon.js forum for a solutions and paste it on the events. Maybe is something impossible, just asking.
For example i searched in their forums how to solve the problem and found this:

So with an event to use native Babylon.js code i can try that solutions in case i can't fix myself with the babylon3D plugin.
