部署到 Goerli 測試網後的錯誤

我在fleek.co 上託管了我的彩票網站，並且在安全帽本地網路上一切正常。所以我決定在 Goerli 上對其進行測試，但我面臨一個又一個錯誤。

起初我得到下面的錯誤 1 並在安全帽配置文件中手動添加了氣體限制。在重新部署合約並在 Flek 上發布後，首先 enterRaffle 工作正常。

當我第二次嘗試進入Raffle 時，它失敗了。其他時候是成功的。但即便如此，它也不會像預期的那樣更新玩家的數量。

我錯過了什麼？

錯誤 1

Error: cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.ethers.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ] (error={"code":-32603,"message":"execution reverted","data":{"originalError":{"code":3,"data":"0x1425571c","message":"execution reverted"}}}, method="estimateGas", transaction={"from":"0x13A19933267ec307c96f3dE8Ff8A2392C39263EB","to":"0x5507C7e274B5201a98141cCd0507cF6e4416Be30","value":{"type":"BigNumber","hex":"0x2386f26fc10000"},"data":"0x2cfcc539","accessList":null}, code=UNPREDICTABLE_GAS_LIMIT, version=providers/5.6.0)

然後像這樣手動添加氣體後，出現錯誤2。

           url: GOERLI_RPC_URL,
           accounts: PRIVATE_KEY !== undefined ? [PRIVATE_KEY] : [],

           //     mnemonic: MNEMONIC,
           //   },
           saveDeployments: true,
           chainId: 5,
           gas: 6000000,
       },

在我看來，它與列舉有關 - 它不會將其狀態重置回 OPEN （我看到它發生在 fullyrandomwords() 函式中。

我的 2 條建議：

1. 確保合約連結到一個訂閱，其中包含足夠的測試連結
2. 這也可能是由於用模數四捨五入 randomWords 數。在fullfillRandomWords()函式中，在第 154 行，您可以嘗試將其更改為：

      uint256 indexOfWinner = (randomWords[0] % s_players.length)*1 ;

我希望這會有所幫助。

氣體估算是通過虛擬執行程式碼來完成的。如果程式碼出錯，應用程序將無法估計氣體。即使您手動設置了 gas 並仍然呼叫該函式，這一次它會在 evm 上執行並且仍然是一個失敗的交易。

在您的情況下，如果應用程序在您呼叫 enterRaffle 時給出“錯誤：無法估計氣體”，或者 RaffleState 在呼叫時未打開或金額小於 i_enteranceFee。
