Hello

map_server works with input from some other process - you need to have a
slam going on 'making the map' then those sensor readings will allow you to
construct the map. Is the gmapping slam_gmapping set to working ? without
any inputs from gmapping slam_gmapping the map_server will not be able to
develop the map.

Regards

Arkapravo
