Invoking a script gives multiple errors

[venvaneless]

When invoking my small script:

// Live Preview copy flair: active copy icon
(() => {
  const PULSE_MS = 1300;

  const isSuccess = (el) => {
    // Obsidian typically flips aria-label to "Copied" and/or sets --text-success
    const aria = (el.getAttribute("aria-label") || "").toLowerCase();
    const style = el.getAttribute("style") || "";
    return aria.includes("copied") || /--text-success/i.test(style);
  };

  const flashCopied = (btn) => {
    if (btn.classList.contains("is-copied")) return;

    // Suppress the top tooltip
    const prevTitle = btn.getAttribute("title");
    const prevAria = btn.getAttribute("aria-label");
    btn.removeAttribute("title");
    btn.removeAttribute("aria-label");

    // Trigger CSS icon + animation
    btn.classList.add("is-copied");

    // Restore everything after pulse
    setTimeout(() => {
      btn.classList.remove("is-copied");
      if (prevTitle != null) btn.setAttribute("title", prevTitle);
      if (prevAria != null) btn.setAttribute("aria-label", prevAria);
    }, PULSE_MS);
  };

  const bindFlair = (btn) => {
    if (btn.dataset._lpCopyBound === "1") return;
    btn.dataset._lpCopyBound = "1";

    // 1) React immediately on click for instant feedback
    btn.addEventListener("click", () => {
      // Let Obsidian handle the actual copying;
      // we handle only the visual state.
      flashCopied(btn);
    });

    // 2) Also observe Obsidian's own success toggle (tooltip/inline style)
    const attrObserver = new MutationObserver(() => {
      if (isSuccess(btn)) flashCopied(btn);
    });
    attrObserver.observe(btn, {
      attributes: true,
      attributeFilter: ["aria-label", "style", "class", "title"],
    });
  };

  const scan = () => {
    document
      .querySelectorAll(".markdown-source-view.mod-cm6 .code-block-flair")
      .forEach(bindFlair);
  };

  // Initial pass + watch for re-renders
  scan();
  const mo = new MutationObserver(scan);
  mo.observe(document.body, { childList: true, subtree: true });

  console.info("LP copy flair icon");
})();

I get this error in the console

I only learn just now Javascript so I'm not well versed yet what might cause it.

Hm, perhaps you meant to report to https://github.com/mnaoumov/obsidian-codescript-toolkit? Because I only see their plugin ID plugin:fix-require-modules.
