Question Can't get State Machine to work with my animation

Hello,
I'm trying to create a simple jump animation for my character with help of the State Machine i found in Assets->Create->DOTS->Animation->State Machine.

I tried to explore all the documentation i can in the different posts on the forum and in the Animation Sample on Github but i'm still stuck with some errors in the Editor mode and a simple crash when i try to go in Play mode.

Here is what i come up with :

The State Machine in Animation Graph :


When i click on the transition arrow :


When i click on the jump motion :


My Player Components in the Inspector ( GameObject in a Subscene ) :


My errors (in Play mode):


If someone make the State Machine Works or have some tips to help me understand my problems and if possible, the path to resolve them, it would be much appreciated !
Thanks,

 

I did not manage to get it to work either, I got a different error if I added a Rig Authoring as well as a rig component but still no luck. Get a lot of errors about OnEnable. I suspect that the gui for the graphs might be broken? I tried five different unity versions but think I am giving up on the gui side of things and will have to dive into setting up the things in code instead. I did get the bones to show up in the rig component in 2020.2 so it showed most promise of the ones I tried so far...
