Hi,

I wrote a trigger to update a field (boolean value) in LEAD when an TASK is added to the lead. Trigger works fine in DEV box but when I deploy it, its giving me Exception error clashing with someother cls in production. I have added both the codes here. Please help me resolve this.

The trigger is below - 

trigger triggerOnLead on Task ( after insert, after update) {
 
    List<Id> leadIds=new List<Id>();

    for(Task t : Trigger.new)
    {

       leadIds.add(t.whoid);
       //system.debug('test' +leadIds);
    }   
       List<Lead> leadList = [Select id, status, isActivity__c from Lead where id =:leadIds and status='Open - Not Contacted' and isActivity__c=false ];
       
       for(Lead l:leadList )
       {
            l.isActivity__c = true;
       }
       
       try{
            update leadList;
          }
       catch(DMLException e){
            system.debug('Lead Activity is not updated properly!.  Error: '+e);
        }
 }

And I'm getting ERROR when deploying:
System.LimitException: Too many SOQL queries: 101
Stack Trace: Trigger.sampleTrigger: line 10, column 1

And it's clashing with trigger -

trigger sampleTrigger on Event(after insert) {

  string sWhtId = trigger.new[0].WhatId;
  string sWhoId = trigger.new[0].WhoId;
  Event objT = [Select id,WhatId,WhoId from Event where id =: trigger.new[0].id ];
 
  if(sWhtId != '')
  {
 
    List<Account>lstAcc = [Select id,LastModifiedById,ownerid from Account where id =: sWhtId ];
    if(lstAcc != null && lstAcc.size()>0)
    {
     if (trigger.new[0].LastModifiedById != null)
     {
      if(lstAcc[0].ownerid != trigger.new[0].LastModifiedById)
      {
        trigger.new[0].IsOwnerSame__c = true;
      }
     }
    else
    {
      if(lstAcc[0].ownerid != trigger.new[0].CreatedById)
      {
        objT.IsOwnerSame__c = true;
      }
    }
    }
    
  }

if(sWhoId != '')
  {
    //Contact
    List<Contact>lstCon = [Select id,LastModifiedById,ownerid from Contact where id =: sWhoId ];
    if(lstCon != null && lstCon.size()>0)
    {
     if (trigger.new[0].LastModifiedById != null)
     {
      if(lstCon[0].ownerid != trigger.new[0].LastModifiedById)
      {
        trigger.new[0].IsOwnerSame__c = true;
      }
     }
    else
    {
      if(lstCon[0].ownerid != trigger.new[0].CreatedById)
      {
        objT.IsOwnerSame__c = true;
      }
    }
    }
  }
 
}
