插入dynamodb时无法解析日期错误？

Question

我正在AWS中做一个小POC。我试图从S3存储桶读取一个csv文件，需要将这些csv文件数据插入到dynamodb中。一切都很顺利，但在第一行本身迭代csv文件数据时，它终止了。

我创建了一个表，即dynamodb内的vehicledata，有一个主键，即veh_price_id。

在得到问题之后，一切都很顺利，直到“我在圈内”。

    //Mocking is not working on ClaimsPrincipal.FindFirst(), so it's fixed 
      by using claim based function:
