AH00112: Warning: DocumentRoot [ ] does not exist - docker

Question

I'm using docker to run an app built with laravel, everything was working fine until for some reason I did a reset to factory default and then built the image again and ran the container but now I'm getting this warning
AH00112: Warning: DocumentRoot [/var/www/html/kh/public] does not exist
though this root does exist and it was working fine before I resetted docker to the factory default.
this is docker-compose.yml file
