  import dataverse success, because I've tested by
  https://github.com/IQSS/dataverse/blob/v5.9/src/test/java/edu/harvard/iq/dataverse/export/ddi/exportfull.xml
  https://github.com/IQSS/dataverse/pull/8483/files#diff-a005f7892fff597838acaabe7cb01d0309a855d8bc77d0d1dabbac08e5495fc0
  the xml sample provided in ddi import docs, or even ddi file exported by dataverse, they all have this problem

v. 5.11.1 build 1069-02e3e92(acutally I tried this function on demo website)

Hi @cokeBeer,
You might want to look at the docs at https://guides.dataverse.org/en/latest/api/native-api.html#import-a-dataset-into-a-dataverse-installation-with-a-ddi-file. At the bottom of this section, it talks about the Subject field and steps needed to add subject.
Note that DDI XML does not have a field that corresponds to the “Subject” field in Dataverse. Therefore the “Import DDI” API endpoint populates the “Subject” field with N/A. To update the “Subject” field one will need to call the [Edit Dataset Metadata](https://guides.dataverse.org/en/latest/api/native-api.html#edit-dataset-metadata-api) API with a JSON file that contains an update to “Subject” such as [subject-update-metadata.json](https://guides.dataverse.org/en/latest/_downloads/46f6461ca67af3fa5e33433146c486b4/subject-update-metadata.json). Alternatively, the web interface can be used to add a subject.

@kuhlaid I've seen this before and tired as it mentioned, but it was still error. Can you give me a http request that can successfully import a DDI ?
