This is due to an underflow bug when the map_name is not provided (parameter octomap_path):

octomap_mapping/octomap_server/src/octomap_saver.cpp

Line 101 in 7b7e8e8

std::string suffix = map_name.substr(map_name.length() - 3, 3);

@wep21 - could you please take a look at this / check for length / throw error?

Hi I am having the same problem , by running ros2 run octomap_server octomap_saver_node -f map.bt ,I get this:
[INFO] [1655901876.946400726] [octomap_saver]: Map received (23542 nodes, 0.050000 m res), saving to
terminate called after throwing an instance of 'std::out_of_range'
what(): basic_string::substr: __pos (which is 18446744073709551613) > this->size() (which is 0)
How should I fix it?
