导出结果不完整

Error message

导出结果不完整

What it means

downloadMarkdownFallback() is the anchor-download path used when the File System Access API is unavailable. It validates its inputs first: a non-empty filename and a string markdown body are required to build the Blob and trigger the download; otherwise it throws "导出结果不完整".

Solutions

1. Ensure the markdown is fully generated (await the export/render step) before calling the fallback.
2. Validate filename and markdown type at the call site and show a user-facing "nothing to export" message.
3. Fix callers that pass (filename, {markdown}) instead of (filename, markdown).
4. Guard with `if (!markdown) return` upstream instead of letting the fallback throw.

Example fix

// before
downloadMarkdownFallback(exportName, maybeMarkdown);
// after
if (typeof maybeMarkdown === "string" && maybeMarkdown.length && exportName) {
  downloadMarkdownFallback(exportName, maybeMarkdown);
} else {
  showToast("导出内容为空，无法下载");
}

if (!filename || typeof markdown !== "string" || !markdown.trim()) { showToast("导出内容为空"); return; }

function isExportReady(filename, markdown) { return typeof filename === "string" && filename.length > 0 && typeof markdown === "string"; }

try { downloadMarkdownFallback(filename, markdown); } catch (e) { if (e.message === "导出结果不完整") showToast("没有可导出的内容"); else throw e; }

When it happens

Trigger: Calling downloadMarkdownFallback(filename, markdown) with filename === ""/null/undefined or markdown not a string (null/undefined/object) — typically when the export pipeline produced no content and the caller passed it through unguarded.

Common situations: Conversation export ran before the transcript finished loading (empty markdown); a refactor changed saveMarkdown's signature and callers pass an options object; clipboard/stream source returned null on failure.

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
