I am trying to retrieve a portion of the response related to a template-based email via a Cloudpage. I am attempting to get the "items" portion of the response. I get the following error:

Value was either too large or too small for an Int32. 

This the section of the overall code that handles the request:

    function retrieveEmailTemplate(accessToken, emailTemplateName, tenantURL)
       var url = 'https://'+ tenantURL +'.rest.marketingcloudapis.com/asset/v1/content/assets/query';

       var contentType = 'application/json';

       var headername = ["Authorization"];

       var headervalue = ["Bearer " + accessToken];

       var payload ='{"query":{"leftOperand":{"property":"name","simpleOperator":"equal","value":"'+ emailTemplateName +'"},"logicalOperator":"AND","rightOperand":{"property":"assetType.name","simpleOperator":"equal","value":"templatebasedemail"}},"fields":["views","data","content"]}';

      try {
        var emailRequest = HTTP.Post(url, contentType, payload, headername, headervalue);

        var emailResult = Platform.Response.Write(emailRequest.Response[0]["items"]);

        return emailResult;

      catch(err) {
        Platform.Response.Write("This is an error: " + err);

This is part of the response I will normally get if I remove the ["items"] part of the emailResult variable:

        "count": 1,
        "page": 1,
        "pageSize": 50,
        "links": {},
        "items": [
                "id": {{REMOVED}},
                "customerKey": "{{REMOVED}}",
                "objectID": "{{REMOVED}}",
                "contentType": "application/vnd.etmc.email.Message; kind=template",
                "assetType": {
                    "id": 207,
                    "name": "templatebasedemail",
                    "displayName": "Template-Based Email"
                "name": "{{REMOVED}}",
                "description": "",
                "owner": {
                    "id": {{REMOVED}},
                    "email": "{{REMOVED}}",
                    "name": "{{REMOVED}}",
                    "userId": "{{REMOVED}}"
                }, ....

Are there any adjustments that need to be made to prevent the error and retrieve the "items" section of the response? Thanks.


You’ll need to parse the response before calling out items.
