eslint --fix 格式化特定的 less 报错

[Yuan-ZW]

Describe the bug

当使用 @antfu/eslint-config 并开启 formatters: true 时, 对以下代码执行 eslint --fix 会报错:

<template>
  <div>test</div>
</template>

<style lang="less" scoped>
.a {
.b {
  .c {
    padding: 1rem;
  }
}
  
}
</style>

注: 其中倒数第三行的空行包含两个空格
执行 eslint --fix 报错:

> eslint --fix test.vue


Oops! Something went wrong! :(

ESLint: 9.15.0

TypeError: Cannot read properties of undefined (reading 'range')

同时, 针对 less 文件:

.a {
.b {
  .c {
    padding: 1rem;
  }
}
  
}

注: 同样倒数第二行的空行也包含两个空格
执行 eslint --fix 之后 less 文件变成:

.a {
  .b {
    .c {
      padding: 1rem;
    }

}

同时报错:

> eslint --fix test.less


D:\YZW\Desktop\minimal-demo\test.less
