为什么方法“匹配”抛出错误未处理的承诺拒绝？

Question

我正试图通过正则表达式查询-/:\/\/s3\.amazonaws.com\/([^\/]+)|:\/\/([^.]+)\.s3\.amazonaws\.com\//获取链接为“ https://darwin-ui-test.s3.amazonaws.com/bundles/bundleAlert”的存储桶名称（darwin-ui-test），但出现错误：{{1 }}

Possible Unhandled Promise Rejection

我希望得到带有键的对象：

const REGEX_BUCKET_NAME =
    '/:\/\/s3\.amazonaws.com\/([^\/]+)|:\/\/([^.]+)\.s3\.amazonaws\.com\//';

const REGEX_BUNDLE_ROUTE = /bundles\/\w+/;

    getBundleAndBucketNames = (link) => {
        const matchesBucket = link.match(REGEX_BUCKET_NAME); // i'm assure, an error occupies here, but i don't know why
        const matchesRoute = link.match(REGEX_BUNDLE_ROUTE);

        return {
            bundleRoute : matchesRoute[0],
            bucketName  : matchesBucket[2]
                ? matchesBucket[2]
                : matchesBucket[1]
        };
    }
getBundleAndBucketNames('https://darwin-ui-test.s3.amazonaws.com/bundles/bundleAlert');

但是我得到了错误：{ bundleRoute : 'bundles/bundleAlert', bucketName : 'darwin-ui-test' }
