删除Firestore文档上Firebase存储中目录的所有文件

Question

exports.deleteItemImages = functions.firestore.document('items/{itemId}')
    .onDelete(async (snap, context) => {
        const deletedValue = snap.data();
        const id = deletedValue.id;

        if (id === null) {
            return null;
        }

        console.log(`itemId to be deleted: ${id}`);

        bucket.deleteFiles({
            prefix: '${id}/'
        }, function (err) {
            if (!err) {
                console.log(`Successfully deleted images with item id: ${id}`);
            } else {
                console.error(`Failed to remove images, error: ${err}`);
            }
        });
    })

我有一个集合items，每个文档都有一个字段id。每个文档都有与之关联的图像，这些图像以相同的文件夹名称id存储在Firebase存储中的目录（文件夹）中。删除各自的Firestore文档后，我想删除Firebase存储中的每个id文件夹。在我的Firebase云功能日志中，行console.log(成功删除的ID为$ {id} );的图像已成功打印，但文件夹删除没有发生

编辑：我尝试手动输入prefix: '${id}/'的文件夹名称，并且它起作用了。因此，连接到Firebase存储不是问题，尤其是该行。

应该是反引号，而不是单引号
