使用Java SpringBoot调用Google Sheets API v4创建表格遇429未超配额错误

我正在使用Java SpringBoot调用Google Sheets API v4创建电子表格，尽管请求配额并未超限，却持续收到429 Too many requests异常。

错误截图显示429请求过量提示。

我的代码如下：

    }
    public static void main(String... args) throws IOException, GeneralSecurityException {

        getData();
        createSpreadsheet("hi");
    }
}

查看云控制台请求指标和配额限制数据，统计显示仅发起了8次createSpreadsheet请求和9次get请求：9次getValues请求全部成功，但8次createSpreadsheet请求均失败，错误信息如下：
