In earlier versions of the "SC Catalog Item" widget the g_form.submit() method call returned a value, which would then execute the submission of the catalog item from what I recall.
if (g_form.submit()) {
// run submission POST API code...
}
In the later versions, g_form.submit() now uses a callback/promise to execute the form submission which POSTS to the catalog item API. So, one would need to run the submission code on that callback to ensure the form is submitted.
g_form.submit();
...
g_form.$private.events.on('submitted', function(){
...
// run submission POST API code
})
However this does not solve the console error but does fix the issue of the form not being able to be submitted.
This "SC Catalog Item" widget I've been working on, has been highly modified and is the first instance of this widget, we're currently on the 3rd iteration of this widget as of New York.
So this fix may only apply to those that maybe using a modified older version of the widget. If not, make sure you're using the later version of the SC Catalog Item widget for the "sc_cat_item" portal page
