Calling Suitelet from afterSubmit of user event script

The suitelet can be called from user event using the modules N/url and N/https. But in the user event, suitelet cannot be called using its internal url in the afterSubmit. The suitelet can be called using the external url which is as follows:

let suiteletCall = url.resolveScript({
                    scriptId: "customscript_jj_sl_render_pdf_dvtb343",
                    deploymentId: "customdeploy_jj_sl_render_pdf_dvtb343",
                    params: {
                        "id": JSON.stringify(id)
                    },
                    returnExternalUrl: true
                });
https.get({ url: suiteletCall });

However, internal url cookie can be retrived in the beforeload and then passed to the afterSubmit to call the suitelet.
