global void execute(Database.BatchableContext BC, List scope){ // Create a map for the chunk of records passed into method. Map<ID, Informe_icex__c> iMap = new Map<ID, Informe_icex__c>((List<Informe_icex__c>)scope);

    List<EventRelation> eRList = [SELECT Id,response,status FROM EventRelation WHERE Id IN 
         :iMap.keySet()];
         
    for(Informe_icex__c i : jobMap.values()){
        
        if(!eRList.isEmpty()){
        i.Comentarios_Invitados__c = eRList.response;
        i.Estado_Invitado__c = eRList.status;
