Mattermost interactive button do not call URL

Hi, I am new to mattermost and I am making a feedback bot for my company to automate feedback process, I need to send an interactive button and when clicked, it must call my bot endpoint: …/message-event/mattermost/interactivity.

I am running mattermost preview docker container in my machine (http://localhost:8065) and my bot is running at http://localhost:4000.

The issue is, when I click the button, it does not call my url, it calls /api/v4/posts/{{post_id}}/action/{{action_id}}, and gives 404 error, see printscreen.

I am trying to solve this issue for almost a day with no success, in documentation I thought I just need to specify the url and that’s it, the button would just call it, but this is not happening, what am I doing wrong here?

Printscreen:

This is the object I am sending to api/v4/posts:

[
   {
      "text":"Olá @userName\nPlaceholder",
      "actions":[
         {
            "id":"message-event",
            "type":"button",
            "name":"Selecionar",
            "integration":{
               "url":"http://localhost:4000/message-event/mattermost/interactivity",
               "context":{
                  "action":"selectUserModal"
               }
            }
         }
      ]
   }
]
