POI anafi AI PointNFly

Hello,
I am trying to achieve a POI with olympe with pointnfly and keep the poi while moving.
I am working with a simulated drone under sphinx.
But when I try to execute the poi, this part of code

expectation_pointnfly_flying = drone(State(idle=dict())).wait(_timeout=10)
if not expectation_pointnfly_flying.success():
print(“PointNFly is not possible even if the drone is flying”)

It returns :
PointNFly is not possible even if the drone is flying

Have you any idea why would it be unavailable ?

Thanks !
