How can you call a suitelet from a user event without making it? I keep getting a 500 error

var suitletURL = url.resolveScript({
    scriptId: 'customscript_osm_sl_sn_trans_order',
    deploymentId: 'customdeploy_osm_sl_sn_trans_order',
    returnExternalUrl: true
});
var response = <http://https.post|https.post>({
    url: suitletURL,
    body: JSON.stringify({recordType: newRec.type, id: afterRec.id}),
    headers:headerObj
});

Any reason you dont use the code from the suitelet inside the user event

@battk whatcya mean?

Take whatever code in the suitelet and run it in the user event instead

ah! I have to save it in a suitelet so that the other user event scripts can be triggered

Same thing, take whatever code is in the other user event and run it in the user event

can't. It's from a non accessible script

use https.requestRestlet with a restlet instead
