BiddableAdGroupCriterion biddableAdGroupCriterion = (BiddableAdGroupCriterion) page.getEntries(2);
///the entry with index 2 comes from for (AdGroupCriterion adGroupCriterion : page.getEntries()) and index=2 has the following information
//Ad group criterion with ad group id "XXX91483XXX", criterion id "BIDDABLE", criterion use "XXX81892XXX", and type "CriterionUserList" was found.
biddableAdGroupCriterion.setBidModifier(new Double(BID_MODIFIER));
// Create operation.
AdGroupCriterionOperation operation
= new AdGroupCriterionOperation();
operation.setOperand(biddableAdGroupCriterion);
operation.setOperator(Operator.SET);
AdGroupCriterionOperation[] operations = new AdGroupCriterionOperation[]{operation};
AdGroupCriterionReturnValue result = adGroupCriterionService.mutate(operations);
However I'm getting the next error.
faultString: [AdGroupCriterionError.CRITERIA_TYPE_INVALID_FOR_BIDDING_STRATEGY_CONFIGURATION @ operations[0].operand.criterion]
Any help?
