Why doesn't the @error event fire in Vue?

Question

Vue.js

The image is not on the page. The console writes
GET localhost:3000/portfolio/someDirection/topMob.jpg 404 (Not Found)

I insert the image itself like this

<img :src="imgSrc" @error="logError" alt="not work" />

Image path

imgSrc() {
            return `../someDirection/topMob.jpg`
  }

Function in @error

logError() {
            console.log("No image")
        }

Interestingly, if I insert a sign after the path into the line with the path before the image, then the directive works. For example:

imgSrc() {
            return `../someDirection/topMob.jpg  ломаю путь`
        }
