[Python] What am I doing wrong with my .ycm_extra_conf.py?

I have successfully installed the YouCompleteMe plugin for vim and it is already working, however, I cannot get it to work on an actual project. For some reason I cannot create a .ycm_extra_conf.py that actually works. To test it out I tried making a minimal project, i.e. I created ~/project with the following structure:

~/project
~/project/.ycm_extra_conf.py
~/project/code
~/project/code/example.cpp
~/project/include
~/project/include/example.hpp


Nothing fancy. When I edit example.cpp I try to #include "example.hpp" but it already fails there because ycm says it cannot find the file ('example.hpp' file not found [pp_file_not_found]). vim does find the .ycm_extra_conf.py file and it tries to load it, however, I am not sure whether it's working correctly.

The output from :YcmDebugInfo is:

My .ycm_extra_config.py looks like this:

import os
import ycm_core

flags = [
'-Wall',
'-O3',
'-I../include',
'-I./include',
]

def FlagsForFile(filename, ** kwargs):
return
{
'flags': flags,
'do_cache': True
}


The output from the temporary log files is as follows. For /tmp/clangd_stderr2sp81d3p.log:
