Answer 1

you can send the same user_id as you are sending in verify_user and add the below function in your user_module then use this function in your controller.

static get_user_by_id = async (req) => {
  try {
      const { user_id } = req.query
      return await models.users.findById(user_id)
  } catch (error) {
      throw error
  }
}

Note that verify_user is expecting a POST request while the above function expect a GET request.
