const rl = require("readline").createInterface({ input: process.stdin });

        let nums = tokens[0];
        let count = tokens[1];
        let arr = new Array(nums).fill(0);
        let flag = false;
        for (let i = 0; i < count; i++) {
            let operate = (await readline()).split(" ").map(Number);
            if (operate[0] === 1) {
                arr[operate[1] - 1] = 1;
            } else {
                for (let j = 0; j < arr.length; j++) {
                    if (j + 1 !== operate[1]) {
                        arr[j] = 1;
                    }
                }
            }
            if (arr.filter((value) => value === 0).length === 0) {
                flag = true;
                console.log(i + 1);
                break;
            }
        }
        if (!flag) {
            console.log(-1);
        }
    }
})();

家人们，我这段代码编译器报 let operate = (await readline()).split(" ").map(Number);这一行数组越界或语法错误，不知道问题出在哪儿了，谢谢！
