Drupal 8.x

Drupal Version: 8.1.7

PHP OS: Red Hat Enterprise Linux

Drush Version: 8.4.0

What I am attempting to do is have a Cron job execute a small BASH script that I've written. This script checks if a particular service is active in my RHEL environment and if it isn't my Drupal site gets put into maintenance mode. There is a Drush command at the start that checks if the site isn't already in maintenance mode and a second Drush command later to put the site into maintenance mode if a few conditions are met. 

The Cron job I set up looks like the following:

I created a base entity using drupal console, and then created the bundles of that entity in the UI. The result is that all of the bundles are under /admin/structure/entity_type/ and to add entities of any of the bundles, I access them via: /admin/structure/entity_type/add. 

Is there a way I can alter the route for each bundle, so for example, the route for each crud action is like this:

/admin/structure/bundle-name1/add
/admin/structure/bundlename1/entityid/edit
/admin/structure/bundlename1/entity/delete

In the callback I assign a number to an integer numeric field, it works because it displays it. When I save the movement the number is not saved.
I did various tests but didn't understand why you don't save it
The field is field_nu_hour_mission (integer)
If I write the number from Tstiera it displays it and stores it

I made an upgrade from Drupal 7 to Drupal 9 and to drupal 8. The upgrade worked by I can't use the fields from "image_ads" content type.

In drupal 8

I get these errors:

Hello I'm new in drupal, I have a problem with drupal 8.4.3. There is a view with CONTEXTUAL FILTERS and RELATIONSHIPS to show documents relatedto the category. The result is showing duplicate items. I tried to use Distinct but it is not working. I tried to use aggregation but I am getting an error as soon as I activationg aggregation filter group together.
