過去幾天我一直在開發一個自動化流程，用來撰寫和傳送完整報價單。使用「HTML 轉 PDF」節點時運作正常，我能夠傳送包含原始未格式化資料的 PDF。但當我嘗試將資料格式化到模板中時，PDF 顯示為空白。我是否遺漏了什麼？{

你的 PDF 出現空白的原因是你在工作流程中混合了兩種不同的 PDF 生成方法。你試圖使用基於範本的方法（透過 PDF Generator API），但你卻提供了二進位檔案（透過「轉換為檔案」節點）並提供了無效的 JSON 資料。
以下是三個具體問題及其修復方法：
轉換為檔案節點會將你的文字轉換為二進位 HTML 檔案。但是，PDF Generator API 節點不會「轉換」現有檔案成為範本；它透過將 JSON 資料合併到預先定義的範本中來建立新檔案。
將 轉換為檔案放在 PDF 產生器之前，你會將輸入從 JSON 物件（API 需要的）變更為二進位物件，這會導致 API 無法找到填充範本所需的資料。
**修復：**刪除 轉換為檔案節點，並直接將 Edit Fields1 連接到 生成 PDF 文件。
- 在你的
生成 PDF 文件節點中，你將資料設定為：={} {{ $json.output }}
這不是有效的 JSON。PDF Generator API 需要一個 JSON 物件，其中鍵必須與你在 PDF Generator API 儀表板範本中建立的預留位置相符。
**修復：**將 data 欄位變更為正確的 JSON 物件。例如，如果你的範本有一個名為 {{quote_content}} 的預留位置，你的資料欄位應該看起來像這樣：
{
"quote_content": "{{ $json.output }}"
}
- 為了讓資料實際出現在 PDF 上，你在 n8n 中使用的鍵必須完全符合範本中的變數名稱（ID：1649628）。
- **如果你的範本是空白的：**表示 API 收到了請求，但在你的 JSON 中找不到任何與設計中的
{{variable}}標籤相符的鍵。 - **建議：**在 PDF Generator API 儀表板中檢查你的範本。如果你有像
{{client_name}}或{{total_price}}這樣的標籤，你必須在 JSON 中特別提供這些：
{
"client_name": "{{ $(\"Edit Fields\").item.json[\"What's your name?\"] }}",
"quote_content": "{{ $json.output }}"
}

在這個引用流程中，隔離空白 PDF 是範本資料還是渲染問題。在 PDF 節點之前，加入一個 Set/Edit Fields 節點，輸出只有一個微小物件，其鍵與一個範本預留位置相符，例如 eventName 和 guestCount，然後執行 PDF 節點。
如果單一欄位 PDF 呈現，範本沒問題，問題在於 AI 輸出形狀；在 PDF 節點之前，將代理輸出解析為具名 JSON 欄位。如果單一欄位測試仍是空白，下一個邊界是範本 ID 或預留位置名稱，而非 n8n 流程。
嘿 Kjooleng
感謝你的回覆。
我已經多次嘗試過你的步驟，但我仍然收到空白範本。我已經更新了範本中的變數以符合我的試算表，並將資料更新為有效的 JSON
我已經從使用 PDF Generator API 的引用範本切換到我建立的空白範本，希望能夠組織好資料。我知道我已經很接近了，但我只需要再做一個缺失的步驟就能讓它運作。
你有任何想法嗎

@Tim_Barrett ，你可以嘗試使用 PDF API Hub 中的節點，它允許你使用範本產生 PDF。
以下是已驗證的節點連結：
