DLC 資金交易錯誤：非強制腳本驗證標誌（見證程序雜湊不匹配）（程式碼 64）

我正在嘗試為 DLC 建構資金交易。到目前為止，我已經創建了以下交易，該交易對 1000/1000 sats 的本地/遠端抵押品的投注條目和二進制贏/輸全有或全無結果進行編碼。

據我所知，交易在輸入/輸出地址等方面是準確的，並且提供了簽名（見下文），但我收到了這個錯誤：

non-mandatory-script-verify-flag (Witness program hash mismatch) (code 64)

嘗試廣播交易時。十六進制：

<txhash>

我還嘗試使用另一個服務進行廣播，該服務有一個更具描述性的錯誤，所以我也會在這裡發布：

Error validating transaction: Error running script for input 0 referencing <hash> at 1: incorrect number of witness items for version 0 witness program of length 20.

我不太確定如何解釋這個錯誤，也不確定如何進行調試，所以任何指針都會非常感激。在 StackExchange 上搜尋這些錯誤似乎並沒有提供任何相關的結果，除了這個答案。用於簽署交易的不正確的私鑰是否可能導致見證程序雜湊不匹配？（正如Andrew Chow 所建議的那樣）。

如果您查看輸入 0，它不包含witness元素，這意味著它沒有簽名。您需要對兩個輸入進行簽名才能進行廣播。
