当我从 ethers.js 调用 play() 函数时交易失败

Question

我正在使用 ethers.js 与部署在多边形测试网上的智能合约进行交互。我尝试从智能合约调用函数 play() 但它总是失败并显示错误：Error: transaction failed [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ]

我已经满足了所有的要求声明，但它似乎仍然失败。我的代码有问题吗？

我也尝试过单独使用 chainlink VRF 的 getRandomNumber() 函数，它在那里工作。

                    const tx = await this.props.futNFTMatch
                      .connect(signer)
                      .play({

您的交易因不足gas而被撤销：

Warning! Error encountered during contract execution [out of gas]

尝试从您的通话中删除 gas 和 gasPrice 字段或增加
