Hyperledger Fabric自定義鏈式代碼調用失敗

Question

我試圖運行自定義鏈式代碼。我是能夠成功地部署，但是當我使用運行調用命令：

peer chaincode invoke -n mycc -c '{"Args":["write","hello_world", "200"]}' 

面對這樣的錯誤消息：對等chaincode的成功部署後

Error: Error endorsing chaincode: rpc error: code = 2 desc = Error deploying chaincode: Failed to launch chaincode spec(Could not get deployment transaction from LCCC for mycc - Error deploying chaincode: Transaction or query returned with failure: transaction not found default/mycc)

日誌（運行在DEV模式等） ：

任何指向我出錯的地方都會很棒。提前致謝。

對invoke語法的一些修改可能會有所幫助。

• 如果啓用了安全性，則應使用-u參數指定已註冊的用戶。
• 對於-n參數，可以嘗試鏈碼ID而不是鏈碼名稱。
