update keyword's bidding not working

Hi,

I try to set(update) keyword's bidding with BatchJobService on PHP.
I create several operation:

foreach ($keywordsData as $keywordData) {
    // Create ad group criterion.
    $adGroupCriterion = new BiddableAdGroupCriterion();
    $adGroupCriterion->adGroupId = $keywordData['adGroupId'];
    $adGroupCriterion->criterion = new Criterion($keywordData['id'], 'KEYWORD');

    // Set bids (optional).
    $bid = new CpcBid();
    $bid->bid = new Money($keywordData['bid'] * self::MICRO_AMOUNT);
    $bid->cpcBidSource = 'CRITERION';

    $biddingStrategyConfiguration = new BiddingStrategyConfiguration();
    $biddingStrategyConfiguration->biddingStrategyType = 'MANUAL_CPC';
    $biddingStrategyConfiguration->biddingStrategySource = 'CRITERION';

    $cpcBiddingScheme = new ManualCpcBiddingScheme();
    $cpcBiddingScheme->enhancedCpcEnabled = false;
    $biddingStrategyConfiguration->biddingScheme = $cpcBiddingScheme;

    $biddingStrategyConfiguration->bids[] = $bid;
    $adGroupCriterion->biddingStrategyConfiguration = $biddingStrategyConfiguration;

    // Create operation.
    $operation = new AdGroupCriterionOperation();
    $operation->operand = $adGroupCriterion;
    $operation->operator = 'SET';

    $operations[] = $operation;
}

There is one of operation:

[4] => AdGroupCriterionOperation Object
    (
        [operand] => BiddableAdGroupCriterion Object
            (
                [userStatus] =>
                [systemServingStatus] =>
                [approvalStatus] =>
                [disapprovalReasons] =>
                [destinationUrl] =>
                [experimentData] =>
                [firstPageCpc] =>
                [topOfPageCpc] =>
                [firstPositionCpc] =>
                [qualityInfo] =>
                [biddingStrategyConfiguration] => BiddingStrategyConfiguration Object
                    (
                        [biddingStrategyId] =>

                        [biddingStrategyType] => MANUAL_CPC
                        [biddingStrategySource] => CRITERION
                        [biddingScheme] => ManualCpcBiddingScheme Object
                            (
                                [enhancedCpcEnabled] =>
                                [BiddingSchemeType] =>
                                [_parameterMap:BiddingScheme:private] => Array
                                    (
                                        [BiddingScheme.Type] => BiddingSchemeType
                                    )

                            )

                        [bids] => Array
                            (
                                [0] => CpcBid Object
                                    (
                                        [bid] => Money Object
                                            (
                                                [microAmount] => 51300000
                                                [ComparableValueType] =>
                                                [_parameterMap:ComparableValue:private] => Array
                                                    (
                                                        [ComparableValue.Type] => ComparableValueType
                                                    )

                                            )

                                        [cpcBidSource] => CRITERION
                                        [BidsType] =>
                                        [_parameterMap:Bids:private] => Array
                                            (
                                                [Bids.Type] => BidsType
                                            )

                                    )

                            )

                    )

                [bidModifier] =>
                [finalUrls] =>
                [finalMobileUrls] =>
                [finalAppUrls] =>
                [trackingUrlTemplate] =>
                [urlCustomParameters] =>
                [adGroupId] => 8427124XXX
                [criterionUse] =>
                [criterion] => Criterion Object
                    (
                        [id] => 41399813XXX
                        [type] => KEYWORD
                        [CriterionType] =>
                        [_parameterMap:Criterion:private] => Array
                            (
                                [Criterion.Type] => CriterionType
                            )

                    )

                [labels] =>
                [forwardCompatibilityMap] =>
                [baseCampaignId] =>
                [baseAdGroupId] =>
                [AdGroupCriterionType] =>
                [_parameterMap:AdGroupCriterion:private] => Array
                    (
                        [AdGroupCriterion.Type] => AdGroupCriterionType
                    )

            )

        [exemptionRequests] =>
        [operator] => SET
        [OperationType] =>
        [_parameterMap:Operation:private] => Array
            (
                [Operation.Type] => OperationType
            )
    )

Then i try to upload it:

$batchJobUtils = new BatchJobUtils($uploadUrl);
$batchJobUtils->UploadBatchJobOperations($operations);

There is an uploading result as XML object:

[result] => SimpleXMLElement Object
    (
        [AdGroupCriterion] => SimpleXMLElement Object
            (
                [adGroupId] => 8427124XXX
                [criterion] => SimpleXMLElement Object
                    (
                        [id] => 41399813XXX
                        [type] => KEYWORD
                        [Criterion.Type] => Keyword
                        [text] => XXXXXXXXXX XXXXXXXX XX
                        [matchType] => PHRASE
                    )

                [AdGroupCriterion.Type] => BiddableAdGroupCriterion
                [userStatus] => ENABLED
                [systemServingStatus] => ELIGIBLE
                [approvalStatus] => APPROVED
                [biddingStrategyConfiguration] => SimpleXMLElement Object
                    (
                        [biddingStrategyType] => MANUAL_CPC
                        [biddingStrategySource] => CRITERION
                        [biddingScheme] => SimpleXMLElement Object
                            (
                                [BiddingScheme.Type] => ManualCpcBiddingScheme
                                [enhancedCpcEnabled] => false
                            )

                        [bids] => Array
                            (
                                [0] => SimpleXMLElement Object
                                    (
                                        [Bids.Type] => CpmBid
                                        [bid] => SimpleXMLElement Object
                                            (
                                                [ComparableValue.Type] => Money
                                                [microAmount] => 7000000
                                            )

                                        [cpmBidSource] => ADGROUP
                                    )

                                [1] => SimpleXMLElement Object
                                    (
                                        [Bids.Type] => CpcBid
                                        [bid] => SimpleXMLElement Object
                                            (
                                                [ComparableValue.Type] => Money
                                                [microAmount] => 100000000
                                            )

                                        [cpcBidSource] => ADGROUP
                                    )

                            )

                    )

            )

    )
)

But bids are not setted from operation bid. And cpcBidSource equal to "ADGROUP", but must be equal to "CRITERION".
Campaing has type "Only Search Network".

Why i can't set the bid to keywords?
What wrong with my code?
