I write the style in the calculation properties in the components of the project. I want to set the background-image of the style dynamically, but I encounter some problems in the process. How can I solve

 data () {
    return {
      tab_active: "ma",
      bgUrl: "@/assets/images/stamps/icon-auditing.png"
    }
  },
  computed: {
    imgStyle () {
      if (this.bgUrl) {
        var img = require(this.bgUrl) //this.bgUrl"@/assets/images/stamps/icon-auditing.png" 
        var url = `url(${img})` 
        console.log(url)
        return {
          "background-image": url,
          "background-position": "center center",
          "background-size": "auto 100%",
          "background-repeat": "no-repeat"
        }
      }
    },
 }   

the error is as follows

the problem has been solved. When accessing resources under the static folder, use the absolute path / static, that is, point to the folder reference without require direct background-image: url ("address")
