Inertia error when running experiment via roslaunch

[erdisayar]

Hi,

When I try to run roslaunch flightros rotors_gazebo.launch , I am gettting the following errors.

• [ERROR] [1641380685.118407413]: Couldn't open joystick /dev/input/js0. Will retry every second.

• gzserver: /var/lib/jenkins/workspace/gazebo9-debbuilder/build/gazebo-9.19.0/gazebo/physics/ode/ODELink.cc:443: virtual ignition::math::v4::Vector3d gazebo::physics::ODELink::WorldLinearVel(const Vector3d&) const: Assertion (this->inertial != nullptr)&& ("Inertial pointer is null")' failed. Aborted (core dumped)

Any idea how to fix these errors ?

Here is the complete log.
