在 ERC721 合約上呼叫 transferFrom() 時出現“錯誤：無法辨識發件人帳戶”

我在將 ERC721 代幣的所有權轉移到已部署的控股契約時遇到問題。

我在執行時遇到的錯誤truffle test如下 -使用已部署的 Holding 合約Error: sender account not recognized呼叫transferFrom()ERC721 合約上的函式時。

我在打電話之前已經成功批准了持有契約，transferFrom()所以這不是問題，但我不知道嘗試將 NFT 轉移到持有契約的錯誤在哪裡。

合約和測試文件位於： https ://github.com/sharad-s/DAOjo

在我的測試中導致此錯誤的特定程式碼行是第 120 行DAOjo/test/test.js

要重新創建此錯誤：

• 複製回購
• 全域安裝松露
• 執行 ganache 本地區塊鏈實例（埠 8545）
• truffle test在這個 repo 的根目錄下執行

以下是錯誤堆棧跟踪：

謝謝！

您只能向from您的節點（在本例中為 ganache）知道私鑰的帳戶發送交易。在這段程式碼中：

const transferFrom = await _HouseNFTRegistry.transferFrom(
   houseOwner,
   _spvHoldingCrowdsale.address,
   1,
   { from: _spvHoldingCrowdsale.address, to: _HouseNFTRegistry.address }
);

您正在嘗試從合約地址發送交易，這是您無法做到的。（沒有人知道該地址的私鑰。）
