Drupal 8.x

Strange URL behaviour drupal 8.9
Next problem I have on a drupal 8.9.5 dev site.
I have a entity with teams and this entity has a text field with the url of the team page (relative link)
On a view of the block type I rewrite the result with this rule:
<a href="{{field_team_link}}">
{field_team_icon_url}}
{{field_team_name}}
</a>

And the link field in the team entity is something like /teampagina/HA1 Where HA1 is the teamcode and this lead to a page with the contextual filter = team_code

I created a small custom module to automatically flag new or updated entities.

My code doesn't work, there must be some errors. Can you help me ? Thank you

I have read through the following options I found. I am not sure which one to choose, when it comes to suitability for initial import, update convenience, future module support etc. Can you please share your experience to help me make my choice:

I have something like the following in mymodule.module:

const MYMODULE_CONST = 42;

/**
 * Implements hook_myhook().
 */
function mymodule_myhook($route_name, RouteMatchInterface $route_match) {
  return(t('The answer is @const', ['@const' => MYMODULE_CONST]));
}

This is the only place I use this constant. The reason for using a PHP global const for this is to have it defined near the top of the file for easy spotting and replacement. So having it as a value inside the function is not an option.

Please pardon the fact I’m an ordinary non-expert (basic programmer but not in-depth expert) and am a friendly interface user for the most part.
