we are using 3x.

I modified the code as below and getting a different error. Is my code correct?

{"error":{"code":405,"messageCode":"GWM_0005","message":"Method not supported.","details":[]}}

            var layersRequest = esriRequest({
                url: portalUrl + "/sharing/rest/content/features/generate",
                content: { 'f': "json", 'filetype': 'shapefile', 'publishParameters': JSON.stringify(params) },
                handleAs: "json"
            });

            layersRequest.then(
                function (response) {
                    console.log("Success: ", response.layers);
                }, function (error) {
                    console.log("Error: ", error.message);
                });

is this in 3x or 4x?

I thought it was 3x because you are using handleAs, but passing a query. In 3x, it's content, not query.

But if you are using 4x, it's query, but you should use responseType, not handleAs.

Hi,

I have added the code through insertCode option. Thanks for letting me know.

Instead of providing code as an attachment, please add it using "Insert code sample". It makes it much easier to read your code and help you.
