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 realize this is from a while ago, but I’ve seen similar issues when the language switcher pulls routes that aren’t rebuilt for custom modules. Have you tried flushing the SEO/URL settings and forcing PrestaShop to regenerate routes after adding your custom dispatcher rules? Also worth checking if your module’s front controller is marked as multilingual in the database. If anyone has found a cleaner fix, I’d love to hear it too
