Unable to visualize octomap in rviz

Hello after following all the steps, I am having trouble in visualizing the octomap in movit, it shows me the error below.

I was also unable to see it in rviz, the main differences are i couldnt find map as a option in the drop down for fixed-frame.

It doesnt allow me to put more than one picture, but here is what I am seeing in the rviz.
