Error executing subflow widget

[tomaslindev]

Hello everyone,
I have a task in the Service Portal that requires creating an "Add external comment" widget. When clicked, a modal opens for entering text. Once filled out, a flow should be launched to insert the comment as a public comment in the primary_ticket. This flow will be launched as a system user, and the public comment will indicate the person who wrote it.

I've already created the button, the modal, and the flow (which works correctly if I test it in the flow test section by giving it a sys_id from a Universal Request and entering the requested inputs). However, when I press submit on the modal, the flow doesn't run. I've checked the client side of the widget and it sends the correct data to the server side. I don't know if the server side of the widget is misconfigured or if the subflow needs to be "Callable by Client API," which is why it can't run (I haven't been able to test this part because it requires adding ACLs, and I don't have security_admin permissions).

Server Side:

// =================== Enviar comentario externo vía subflow ===================
if (input && input.action === 'add_external_comment') {
    gs.info('INPUT desde cliente: ' + JSON.stringify(input));
 
    var urSysId = input.ur_sys_id;
    var commentText = input.comment_text;
 
    if (!urSysId || !commentText) {
        gs.error('Faltan datos: ur_sys_id o comment_text');
        data.result = 'missing_data';
        return;
    }
 
    try {
        var inputs = {
            'comment': commentText,
            'ur_sys_id': urSysId
        };
 
        var flowAPI = new sn_fd.FlowAPI();
        var execution = flowAPI.startSubflow('[ATC]Add External Comment to UR', inputs, 'system');
 
        if (execution) {
            gs.info('Subflow lanzado correctamente: ' + execution.getId());
            data.result = 'comment_launched';
        } else {
            gs.error('No se pudo lanzar el subflow');
            data.result = 'subflow_error';
        }
 
    } catch (e) {
        gs.error('Error al ejecutar el subflow: ' + e.message);
        data.result = 'exception';
    }
 
    return;
}

Client Side:

 // ========== External Comment Modal ==========
    c.openCommentModal = function() {
        c.externalCommentText = '';
 
        var options = {
            size: 'md',
            scope: $scope,
            backdrop: 'static',
            templateUrl: 'add-external-comment-template.html'
        };
 
        instance = $uibModal.open(options);
        instance.rendered.then(function() {
            var modal = $('div.modal');
            modal.attr('aria-labelledby', 'modal-title');
        });
    };
 
    // ========== Submit External Comment ==========
   
    c.submitComment = function() {
        if (!c.externalCommentText || c.externalCommentText.trim() === '') {
            spUtil.addErrorMessage("El comentario no puede estar vacío.");
            return;
        }
 
        c.server.update({
            action: 'add_external_comment',
            comment_text: c.externalCommentText.trim(),
            author_name: c.data.currentUserName,
            ur_sys_id: c.data.ur_sys_id
        }).then(function(response) {
    var result = response && response.data ? response.data.result : null;
 
    if (result === 'comment_launched') {
        spUtil.addInfoMessage("Comentario enviado correctamente.");
        c.cancel();
    } else {
        spUtil.addErrorMessage("Error al lanzar el subflow. Código: " + result);
    }
});
    };
}

did you copy the correct code snippet?

This is the code that generates "Code snippet to execute this Subflow", but I don't know where and how I should implement it in my code.

(function() {
	
	try {
		var inputs = {};
		inputs['author_name'] = ; // String 
		inputs['comment_text'] = ; // String 
		inputs['ur_sys_id'] = ; // String 

		// Start Asynchronously: Uncomment to run in background. Code snippet will not have access to outputs.
		// sn_fd.FlowAPI.getRunner().subflow('global.atcadd_external_comment_to_ur').inBackground().withInputs(inputs).run();
				
		// Execute Synchronously: Run in foreground. Code snippet has access to outputs.
		var result = sn_fd.FlowAPI.getRunner().subflow('global.atcadd_external_comment_to_ur').inForeground().withInputs(inputs).run();
		var outputs = result.getOutputs();

		// Current subflow has no outputs defined.		
	} catch (ex) {
		var message = ex.getMessage();
		gs.error(message);
	}
	
})();

@tomaslindev 

it should go in server side script of widget.

If my response helped please mark it correct and close the thread so that it benefits future readers.

I know it has to go on the server side, but should I remove what I currently have in the Server Script and just use the "Code snippet to execute this Subflow"?
