Hi

One profile does cannot convert Leads in UAT and Production. Is this an access issue on the profile or something on the Opportunity Triggers?

Sys Admin (me) can convert leads fine

error that the user recieves
"Error: There was an error converting the lead. Please resolve the following error and try again: OpportunityTriggers: execution of AfterInsert caused by: System.DmlException: Insert failed.

I have looked at Triggers as listed in the debug log, but i am not sure exactly what i am looking for.  I don't see reference ot the profile anywhere
01p6F000006HWOz|OLOpportunityTeamCreator.createOppTeamMemberForOL(List<Opportunity>)
01p6F000006SKst|OpportunityAfterInsertTriggerHandler.mainEntry(TriggerParameters)
01p6F000006SKt2|TriggerDispatcherBase.execute(ITriggerHandler, TriggerParameters, TriggerParameters.TriggerEvent)
01p6F000006SKsy|OpportunityTriggerDispatcher.afterInsert(TriggerParameters)
01p6F000006SKt4|TriggerFactory.execute(ITriggerDispatcher)

i have debug logs for the profile that is failing 

i have debug logs for me that are allowing to convert the Lead.

what is the best way to figure out where i need to change the access?  The logs are long and this is my first time looking at debug logs. 

UAT refresh Dec 22nd - only change in environments

thank you
