Hello Everyone

I stumbled across a squite painful problem.

I built a skuidpage which calls a apex to send mails upon buttonclick. It all works perfectly fine in Sandbox, but we pushed it to a live org and it just plain out fails

i get this error in the console:

the Apex looks as follows:

public class SendMailsToParticipants{ 

@InvocableMethod    

static void SendMails(List<string> emails) {  

static void SendMails(List emails) {

    String eventId = recipients[0];

    Event e = [SELECT id FROM Event WHERE id = :eventId];

    

    recipients.remove(0);

    

    List<messaging.singleemailmessage> mailList =  new List<messaging.singleemailmessage>();

    

    for(String recipient : recipients){

        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();mail.setTemplateId([select id from EmailTemplate where developername='EventUpdatedEmail'].id);mail.setTargetObjectId([SELECT id FROM User WHERE id = :recipient].id);mail.saveAsActivity = false;mail.setWhatId(e.id);mailList.add(mail);

    }

    

    Messaging.sendEmail(mailList); 

}   

} String recipients = emails.get(0).split(‘,’);</messaging.singleemailmessage></messaging.singleemailmessage>

i can’t figure out why its failing, the users have rights and i use the exat same data to test on live as on sandbox

Any ideas?
