SEO Friendly URL not working when switching Language

[Carpe_diem]

Hi guys,

I am currently working on a custom module and I am having a problem with the SEO friendly URLs. If I go directly to my page recepies mysite.com/si/recepti/sladice/jabolcni-strudel it works fine, but when I change the language with the prestashop default language switcher to lets say italian it displays the italian version of the recipe but my url is not mysite.com/it/recepti/desset/strudel-di-mele but it is mysite.com/it/module/recipes/recipe?category_rewrite=dessert&rewrite=strudel-di-mele 
Can someone please help me solve this. I am attaching my code:
 

 // Here is my routes method in main module file:
  public function hookModuleRoutes($params)
    {

     return [
         'recipes-recipe' => [

                    'param' => 'category_rewrite'
                ],
                'rewrite' => [
                    'regexp' => '[_a-zA-Z0-9-\pL]*',

Dis you translate your front controller in SEO & url?

Do not understand what you mean if I translate front controller? If each language has its own controller? Then no, do I have to create a seperate controller for each language?

If you have a front controller name myslug when you go to SE & url you can edit your front module controller dans change slug url for each language

Ok, I understand for single page, but I have a lot of recipes not just the one I mentioned in my first post, I tried to add recept/{category_rewrite}/{rewrite} in SEO & URLs but I get an error,

I’ve hit the same snag before, and it usually boils down to language rewrite rules not being rebuilt after adding custom routes. Clearing cache and forcing a full Regenerate SEO & URLs in the back office often fixes it, but in some cases I had to re‑register routes in the module’s install method too. By the way, https://crowdo.net/blog/ai-search-revolution-website-still-matters/ has some handy context on keeping URL structures clean for SEO.
