How to store resources in json format into IRIS through DTL model

您好，我想问一下为什么我无法通过Iris中的内置转换模板将从HAPI-FHIR服务器下载的患者资源转换为SDA格式。它总是表明缺少某个默认值，或者这就是我们需要更改格式吗？我想问一下我们如何快速创建自己的映射，以及如何通过json将所需的数据转换为sda并将其存储在iris中，然后我们可以通过齐柏林飞艇进行调用，非常感谢您解决我的问题问题

Transaltion for the question:

Hello, I would like to ask why I am unable to convert patient resources downloaded from the HAPI-FHIR server to SDA format via the built-in conversion template in IRIS. It always indicates that some default value is missing, or is this the format we need to change? I would like to ask how we can quickly create our own mapping and how we can convert the required data to sda via json and store it in iris, which we can then call via Zeppelin, thank you very much for solving my problem.
