uni.createSelectorQuery用class获取nodeRef有什么要求吗？

微信开发者工具中

export const getViewRectInfo = (className, callback) => {  
    // console.log(className);  
    let query = uni.createSelectorQuery();  
    return new Promise((resolve) => {  
      query  
        .select("." + className)  
        .boundingClientRect(data => {  
            // console.log(data);  
          const result = {  
            width: data.width,  
            height: data.height,  
            top: data.top,  
            bottom: data.bottom,  
            left: data.left,  
            right: data.right,  
          };  
          callback(result); // 调用回调函数，并传递结果对象  
          resolve(result); // 返回结果对象  
        }).exec();  
    });  
  };

这是fixed-section的定义

<template>  
  <view class="fixed-section">  
    <slot></slot>  
  </view>  
</template>  

<script setup>  
</script>  

<style lang="scss" scoped>  
.fixed-section {  
  position: sticky;  
  top: 0;  
  left: 0;  
  right: 0;  
  z-index: 999;  
  // background: white;  
}  
</style>

getViewRectInfo获取类top和bottom的时候正常，获取类section的时候，select不到，请问可能是什么原因造成的，我的uniapp版本
