Bodymovin - Lottie in Rails project : json in not found

Question

As in the tutorial here : https://aescripts.com/bodymovin/ I try to render my svg in my rails project. I think I can find the player but not the json : My typescript file looks like this :

const bodymovin = require("../player/securite.js");

const animation = bodymovin.loadAnimation({
      container: document.getElementById('json-test'),
      renderer: 'svg',
      loop: true, 
      autoplay: true, 
      path: "app/json/securite.json"
})

With that, I have the error 404 (Not Found). I also tried to put my json file in my Javascript folder: same result, in my assets: same result. Do you know where I should put my json file in my project rails ? Also using gulp, is there any compatibility issue ?
