Model not displayed on Gazebo

Hello. This may be a little confusing because I am using a translator.

I was trying to simulate my robot using Gazebo and MoveIt2. I can use Rviz to view models from urdf files, and I can use MoveIt2 and Rviz for planning, but I just can't get Gazebo to display them.

Here is the urdf file, the launch file, and the results of the run.Please, could you think together with me? After I spawn an entity, gzserver freezes for about 2 minutes, and then I can see the joints, controllers, etc. in Gazebo, but the model does not show up.


waiting gazebo:

$ env | grep ROS
