当我从 ethers.js 调用 play() 函数时交易失败

Transaction fails when I call the play() function from ethers.js

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。
