Rviz error. Transform [sender=unknown_publisher] For frame [atom/hokuyo]: Frame [atom/hokuyo] does not exist

asked 2022-12-16 09:53:37 -0500

I have ROS melodic and I have been trying to use the hokuyo lidar, but rviz shows the aforementioned error. All the solutions elsewhere were for from frame to fixed frame transform errors, in the GlobalOptions also I have changed the FixedFrame option from [FixedFrame] to 'robot_footprint', but still the problem is present. Please help if possible.
