Asset API (post request) for creation of content fragment is not working in AEM6.5

I have a CF model linked to a CF folder under DAM. When I create a CF manually using the Touch UI, it works perfectly, and I can create and retrieve the CF successfully. However, when I try to create a CF using the Asset API, I receive a 500 error response. Upon checking the logs, I found the following error.

POST /api/assets/content-management/country-mapping/test.json HTTP/1.1] com.adobe.granite.rest.impl.servlet.PostRequest Exception during request processing.

Hi @nishanth_kr ,

 

I was able to create a CF using below JSON

{ "properties": { "contentFragment": true, "name": "test", "cq:model": "/conf/global/settings/dam/cfm/models/product-data", "title": "test", "description": "test", "elementsOrder": [ "someData1", "someData2" ], "elements": { "someData1": "dfdf", "someData2": "abc" } } }

 But when I added some rubbish data on "elements" which are not part of the CF Model, it gives me a 500 Response.

Maybe there's a mismatch between the data or data type with the CF Model & the CF you are trying to create.

Ps- I tried it on AEM as a cloud.

Hi @nishanth_kr ,

 

Can you confirm you are using these APIs correctly to create the CF ?

    @anupampatYes, I am using the API format specified in the Swagger documentation. Here is the JSON data for the request and body that I am trying to post to create the CF.

    Request URL : 

    http://localhost:4502/api/assets/content-management/country-mapping/test.json


    Request body:

    { "properties": { "contentFragment": true, "name": "test", "cq:model": "/conf/my-content-fragments/settings/dam/cfm/models/country-number-mapping", "title": "test", "description": "test", "createdBy": "admin", "created": 1737115187690, "modifiedBy": "admin", "modified": 1737115187690, "elementsOrder": [ "country", "phoneNumber" ], "elements": { "country": { "variationsOrder": [], ":type": "string", "variations": {}, "dataType": "string", "title": "country", "multiValue": false, "value": "India" }, "phoneNumber": { "variationsOrder": [], ":type": "string", "variations": {}, "dataType": "string", "title": "Phone Number", "multiValue": false, "value": "1111111111" } } } }
