So, this is the final code which worked for me as able to complete the Trailhead challenge.

trigger OrderEventTrigger on Order_Event__e (after insert) {
    List<Task> tasks = new List<Task>();
    for (Order_Event__e event : Trigger.New) {
        if (event.Has_Shipped__c == true) {
            Task ts = new Task();
            ts.Priority = 'Medium';
            ts.Status = 'New';
            ts.Subject = 'Follow up on shipped order ' + 
                event.Order_Number__c;
            ts.OwnerId = '';
            tasks.add(ts);
        }
   }
    
    insert tasks;
}

Please note in inverted comma next to OwnerId put any active user's id.

You can use the UserInfo.getUserId() to get active user id
  
trigger OrderEventTrigger on Order_Event__e (after insert) {
    List<Task> tasks = new List<Task>();
    for (Order_Event__e event : Trigger.New) {
        if (event.Has_Shipped__c == true) {
            Task ts = new Task();
            ts.Priority = 'Medium';
            ts.Status = 'New';
            ts.Subject = 'Follow up on shipped order ' + 
                event.Order_Number__c;
            ts.OwnerId = userinfo.getuserid();
            tasks.add(ts);
        }
   }
    
    insert tasks;
}

Let us know if this will help you

Hello! This is my code, can you tell me why doesn't work?? 
trigger OrderEventTrigger on Order_Event__e (after insert) {
    
    List<Task> task= new List<Task>();
    
    User owner=[select id from User where Name='Fabrizio' limit 1];
    
    for (Order_Event__e event : Trigger.new){
        if(event.Has_Shipped__c == true){
            Task tsk= new Task ();{
            tsk.Priority = 'Medium';
            tsk.Status = 'New';
            tsk.Subject = 'Follow up on shipped order ' + event.Order_Number__c;
                tsk.OwnerId = owner.id;}
            
            task.add(tsk);
            
        }
    } 
    insert task;
}

PLEASE LET ME KNOW!!

Hi Lorenzo Calò,

Dnt query record. Try to use userinfo.getuserid(); to get user Id. Try to update your code like below 
trigger OrderEventTrigger on Order_Event__e (after insert) {
    
    List<Task> task= new List<Task>();
    
    //User owner=[select id from User where Name='Fabrizio' limit 1];
    
    for (Order_Event__e event : Trigger.new){
        if(event.Has_Shipped__c == true){
            Task tsk= new Task ();
            tsk.Priority = 'Medium';
            tsk.Status = 'New';
            tsk.Subject = 'Follow up on shipped order ' + event.Order_Number__c;
            tsk.OwnerId = userinfo.getuserid();
            task.add(tsk);            
        }
    } 
    insert task;
}

Let us know if this will work

I'm not sure if everyone knows this but setting the OwnerId = UserInfo.getUserId(); will not set it to the user that submitted the platform event.  It will set it to the "Automated Process" users id, which is a special user in salesforce.

Olá amigos, a minha solução ficou assim:  
trigger OrderEventTrigger on Order_Event__e (after insert) {
    List<Task> tasks = new List<Task>();
    	for(Order_Event__e event : Trigger.New) {
        	if (event.Has_Shipped__c == true) {
            	Task task = new Task();
            	task.Priority = 'Medium';
            	task.Status = 'New';
            	task.Subject = 'Follow up on shipped order '+event.Order_Number__c;
            	task.OwnerId = event.CreatedById; 
            	tasks.add(task);
        		}
   		}    
    		insert tasks;
}

Abraços.

try this out : 
trigger OrderEventTrigger on Order_Event__e (after insert) {
    List<Task> taskList = new List<Task>();
    for(Order_Event__e event : Trigger.new){
        if(event.Has_Shipped__c == true){
             Task taskObj = new Task();
            taskObj.Priority='Medium';
            taskObj.Status='New';
            taskObj.Subject='Follow up on shipped order '+event.Order_Number__c ; 
            taskObj.OwnerId =Userinfo.getUserId() ;
            taskList.add(taskObj);
        }
    }
     insert taskList ;
}
