Crazyflie + Vicon Integration

We trying to set up our existing Vicon system for Crazyflie with PX4Firmware.
We are sending the current position (x, y, z) of the drone using the MOCAP message (1Hz).

But it seems like the crazyflie is not able to get position lock.
The take-off command keeps failing.

Also, it is not publishing local_position_ned message.

Any help will be highly appreciated. We have spent almost 2 days trying to figure out all configurations.
