Unable to get amcl3d_node working

[impaidk]

I'm trying to get the pose of my UAV using amcl3d and also simultaneously trying to get the pose info using p3d gazebo plugin.

When I try to echo about the topic /amcl3d_node/range is get the following error. The error is same for other amcl3d topics as well.

rostopic echo /amcl3d_node/range
WARNING: no messages received and simulated time is active.
Is /clock being published?

Then I tried to get info about the amcl3d_node, I get the following error.

rosnode info /amcl3d_node

We checked all the paths and there is no problem with that.
