Bitnami Akeneo clear cache after installing custom bundle

[BiljanaNS]

Hello,
I am very new at Akeneo and I've been trying to install very simple bundle to a bitnami app instance on my akeneo bitnami VM. I've followed all installation directions as in documentation and once I cleared the cache I could no longer run the application. I got this message:

The adnd.bitnamiapp.com page isn’t working
adnd.bitnamiapp.com is currently unable to handle this request.
500

I followed steps in bitnami akeneo documentation no additional steps on my own.
So, I found here this could be permission issue and run this:
sudo chmod -R 777 web/cache
sudo chmod -R 777 var/cache
sudo chgrp -R daemon vendor

At first, it seemed this did the trick and I got Akeneo login page. But, when i logged in I got just empty page with this message in first line:
Hello World!

and that was it. Does anyone know what went wrong with this clear cache? I just tried to install new measure, added and registered bundle, configured in yml, and cleared cache with
php bin/console cache:clear
but I did not delete all translation files inside of
/web/js/translation/
as instructed. Followed this page
https://docs.akeneo.com/2.0/manipulate_pim_data/catalog_structure/how_to_add_a_custom_unit_of_measure.html
Where did my app go? Thanks in advance!

Update: I did not forget to edit routing.yml, I removed the path for my bundle but I am not sure what to do with routing inside of this bundle. It has only defaults row which points to controller.
Still just "Hello World".
