Why does PHP Storm display this message: cannot resolve file?

Question

phpstorm

Good afternoon, dear experts. I'm studying Vue.js here and now PHP Storm does not allow me a file. cannot resolve file

actually here is the imageSrc code:

{
        text: "Привет мир",
        imageSrc: "../../assets/img/fon.webp",
        id: "1"
      },

Please tell me what is the reason?
