Receiving an error while saving the databse file

[rafism1997]

Hi @huuanhhuynguyen ,

I am able to get a small 3d map in rtabmapviz but my graph view seems to be vacant and also my db file is 0 MB size even after mapping. An error is coming up in the command line which is :

rtabmap: Saving database/long-term memory...done! (located at /home/robond/.ros/rtabmap.db, 0 MB)

Can you please help me out with this? I have cloned your project and tried once more, but the same error is coming up.

Thanking you in advance.
