Question

We created an opportunity and expected it to have an associated task, but it didn’t. Make sure your trigger inserts the task into the database

2 3 4 5 6 7 8 9 10 11 12 13 14 15 trigger ClosedOpportunityTrigger on Opportunity (after insert,after update) { List taskListToInsert = new List();

    for(Opportunity opp : [Select Id,StageName from Opportunity 
                              where Id in :Trigger.New AND StageName = 'Closed Won'])
    {
            taskListtoInsert.add(new Task(Subject ='Follow Up Test Task',WhatId = opp.Id));

    }

if(taskListtoInsert.size()>0)
{
    insert taskListtoInsert;
}

}

Answer 1

Instead this line

 List taskListToInsert = new List();

try this

 List<Task> taskListToInsert = new List<Task>();

You should also check if you have any process builder activated that may be causing this problem
