The script will be executed for each selected item, and saving item is always called by plugin. So maybe just:

/**
 * Extract Abstract Keywords
 * @author Polygon
 * @link https://github.com/windingwind/zotero-actions-tags/discussions/136
 */
const window = require("window");
const console = window.console;
let n = 0;
if ((await item.getBestAttachmentState()).exists == false) {
  return;
}
const pdfItem = await item.getBestAttachment();
if (!pdfItem) {
  return;
}
const text = (await Zotero.PDFWorker.getFullText(pdfItem.id, 2, true)).text;
const res = text.match(/\n(Abstract[\s\S]+?)\nKeywords(.+)/i);
if (res && res.length == 3) {
  const data = {
    abstract: res[1]
      .replace(/^abstract:?\s*/i, "")
      .replace("\n", " ")
      .replace(/\s+/, " "),
    keywords: res[2]
      .replace(/^\s*:\s*/, "")
      .trim()
      .split(/[;,]\s*/)
      .map((i) => i.trim()),
  };
  console.log(data);
  await Promise.all(
    data.keywords.map(async (tag) => {
      item.addTag(tag);
    })
  );
  item.setField("abstractNote", data.abstract);
}

return "Extracted item keywords and abstract.";

你好，运行该脚本没有报错，但是也没有提取出关键词是什么原因呢？PDF文件是使用Zotfile另存的，不是存在Zotero内部的，会有影响吗

跟PDF格式有关，const res = text.match(/\n(Abstract[\s\S]+?)\nKeywords(.+)/i); 是正则匹配，如果没有提取到 Keywords: 这个字符串就没有办法提取关键字。不同出版商的PDF格式不同，IEEE很多的都是 Index Items-，需要改成：
const res = text.match(/\n(Abstract[\s\S]+?)\nIndex Terms—(.+)/i);
