Hi below is my class and wrapper class

public class manageProductsController {
    
    @AuraEnabled
    public static string insertOpportunityLineItems(String oppId,list<Prodsearch> selctdProdList){
        system.debug('####SELTDPRODlIST####'+selctdProdList);
        system.debug('*****oppId*****'+oppId);
        
        system.debug('=====BEFORE FOR LOOP====');
        for(Prodsearch ps:selctdProdList){
            system.debug('=====IN FOR LOOP====');
            string [] prodPricBookIds = ps.issueCode.split('-');
            system.debug('IDIDIDIDIDIDID'+prodPricBookIds);
           opportunityLineItem oli = new opportunityLineItem();
            oli.OpportunityId = oppId;
            oli.Product2Id = prodPricBookIds[0];
            oli.Quantity=1;
            oli.UnitPrice=10;
            insert oli;
        }
        return null;
    }
    
    public class Prodsearch{
        @AuraEnabled
        public list<string> prodFamily{get;set;}
        @AuraEnabled
        public string subProd{get;set;}
        @AuraEnabled
        public  string issueCode{get;set;}
        
    
    }
   
}

I'm getting the following data in the debug
|####SELTDPRODlIST####({prodFamily=LDP-V, subProd=LDP-V BASIC, issueCode=01t28000000fLaDAAU-01u28000001Dx58AAC})
|*****oppId*****0060K00000TxL2g

but execution is getting fauiled before FOR LOOP with exception

FATAL_ERROR System.UnexpectedException: Salesforce System Error: 1026148476-352 (-230392578) (-230392578)

Please help me on this,

Thanks
Hitesh
