Download DOR attachments using REST API

Hi experts,

I'm trying to use REST API as alternative of download DOR attachments using GenericSoapPort wsdl services.

In particular, I'm trying to use API to download all attachments for a given DocumentOfRecordId and I'm passing the body as represented below:

{"query":"DocumentOfRecordId=300000009005243"}

I'm getting HTTP 200 as HTTP STATUS and response is:

{    "result": ""}

but I'm unable to download any attachment for the given Document Of Record Id

The DocumentOfRecordId contains attachments as reported below:

{    "items": [        {            "AttachedDocumentId": ——-,            "LastUpdateDate": "2024-07-26T09:34:55.679+00:00",            "LastUpdatedBy": "————",            "DatatypeCode": "FILE",            "FileName": "dor_test.pdf",            "DmFolderPath": null,            "DmDocumentId": "———-",            "DmVersionNumber": "——",            "Url": null,            "CategoryName": "MISC",            "UserName": "Varie",            "Uri": null,            "FileUrl": "———",
