ArticulationAction shape mismatch

I am doing a tutorial on controlling a Franka robot joint in Extensions.

As in the code above, if a list is entered as joint_positions in ArticulationAction, it works normally.

But When I use numpy as input, I got an error.

However, when using jetbot, both numpy and list work (joint_velocities).

Why does franka get an error?

I did as you said and it works find. Thanks so much!.
