Thanks Jose, indeed I've probably something not logic in my scene, I'll take a look !
Finally for the second point, I just tried my code on the last version of Obi (5.5) and I don't have the error. So yes, I think that's is probably an issue with my version of Obi (5.2) or Unity (2019.2). But for technical reasons I prefer to stay on Unity 2019.2, so I will not upgrade to the 5.5 which is tagged 2019.3.1 on the asset store.
That's strange because before I didn't have this error, it suddenly appeared. I wonder if my Obi plugin is probably corrupted. I would appreciate it if you could send me the 5.2 version or the last version compatible with Unity 2019.2.7. I will mail you on the Obi support email.
Thank you !
