I am updating the asset in SFMC using the below mentioned API / SSJS code :

var assetIdToUpdate = "115271"; // Replace with the actual asset ID you want to update var assetHTML = rest_instance_url + "/asset/v1/content/assets/" + assetIdToUpdate; var headerNames = ["Authorization"]; var headerValues = ["Bearer " + accessToken]; var contentType = 'application/json' var assetHTMLresponse = HTTP.Get(assetHTML, headerNames, headerValues); var assetHTMLcode = assetHTMLfinalresponse.views.html.content; var assetHTMLname = assetHTMLfinalresponse.name; var assetHTMLdescription = assetHTMLfinalresponse.description; var assetHTMLID = assetHTMLfinalresponse.assetType.id; var payload = { name: assetHTMLname, description: assetHTMLdescription, channels: { email: true, web: false }, assetType: { name: "htmlemail", id: assetHTMLID }, views: { html: { content: assetHTMLcode } } }; var req = new Script.Util.HttpRequest(assetHTML); req.emptyContentHandling = 0; req.retries = 2; req.continueOnError = true; req.contentType = "application/json" req.setHeader("Authorization", headerValues); req.method = "PATCH"; // Use PATCH method for updating existing resources req.postData = String(payload); var resp = req.send(); var resultJSON = Platform.Function.ParseJSON(String(resp.content)); Write(Stringify(resultJSON)); 

However when I publish the cloud page I am getting the below mentioned error

{"message":"Unable to retrieve security descriptor for this frame.","description":"System.InvalidOperationException: Unable to retrieve security descriptor for this frame. - from mscorlib\r\n\r\n"}
