## Post #1 by @vijay_zharotia

I tried posting data from https://specifications.openehr.org/releases/ITS-REST/latest/ehr.html#tag/EHR
{
  "archetype_node_id": "openEHR-EHR-EHR_STATUS.generic.v1",
  "name": {
    "value": "EHR status"
  },
  "uid": {
    "_type": "OBJECT_VERSION_ID",
    "value": "8849182c-82ad-4088-a07f-48ead4180515::openEHRSys.example.com::1"
  },
  "subject": {
    "_type": "PARTY_SELF"
  },
  "is_queryable": true,
  "is_modifiable": true
}

it is giving following error
{
    "error": "Bad Request",
    "message": "Could not resolve subtype of [simple type, class com.nedap.archie.rm.RMObject]: missing type id property '_type'\n at [Source: (String)\"{\"archetype_node_id\":\"openEHR-EHR-EHR_STATUS.generic.v1\",\"name\":{\"value\":\"EHR status\"},\"uid\":{\"_type\":\"OBJECT_VERSION_ID\",\"value\":\"8849182c-82ad-4088-a07f-48ead4180515::openEHRSys.example.com::1\"},\"subject\":{\"_type\":\"PARTY_SELF\"},\"is_queryable\":true,\"is_modifiable\":true}\"; line: 1, column: 271]"
}

any suggestion?

You need to include the _type of the name attribute. See this example which has some handlebar' type 'varaibles in it

```javascript
       const ehrStatus = {
            _type: "EHR_STATUS",
            archetype_node_id: "openEHR-EHR-EHR_STATUS.generic.v1",
            name: {
                _type: "DV_TEXT",
                value: "ehr status"
            },
            subject: {
                external_ref: {
                    id: {
                        _type: "HIER_OBJECT_ID",
                        value: '{{subjectId}}',
                    },
                    namespace: '{{subjectNamespace}}',
                    type: "PERSON" // This is overwiritten to 'PARTY_REF' in BetterCDR
                }
            },
            // If not specified these default to false in EhrBase and true in BetterCDR
            is_modifiable: true,
            is_queryable: true
        }
```

  },
  "subject": {

The data structure is based on the EHR_STATUS class
