    "error": {
        "type": "Whoops\\Exception\\ErrorException",
        "message": "Undefined index: popovers",

The following code throws the exception when querying the data via AJAX.

class Superfecta extends FreePBX_Helpers implements BMO {
....
	public function ajaxHandler() {
		...
		return array("status" => true, "html" => $this->showPage("superfecta.add"));
		...
	}

	public function showPage($page, $params = array()) {
		...
		return load_view(__DIR__.'/views/view.superfecta.grid.create.php');
		...
	}
		
...

}

File (_DIR_.'/views/view.superfecta.grid.create.php):

....
<div class="col-md-9"><?php echo drawselects('', 0, FALSE, FALSE)?></div>
....

JS code to query the data:

var post_data = {
	module: "superfecta",
	command: "dialog_new_scheme"
};
$.post(window.FreePBX.ajaxurl, post_data, function(data) {
	if (data.status) {
		$(body).html( data.html );
	} else {
		fpbxToast(data.message, '', "error");
	}
})
.fail(function(xhr, textStatus, errorThrown) {
	fpbxToast(xhr.responseText, '', "error");
});
