fieldMaskError: "FIELD_HAS_SUBFIELDS" when updating campaign bidding strategy

[Quan Zhang]

Hi,

I'm using .NET sdk to create and update a Google Campaign and met the following issue:

I'm using the following way to create a campaign with MaxClicks bidding scheme and everything goes well:

campaign.BiddingStrategyType = BiddingStrategyType.TargetSpend;

campaign.TargetSpend = new TargetSpend();

However, when I try to update a campaign (without any actual) like:

campaign.ResourceName = campaignResourceName;

campaign.BiddingStrategyType = BiddingStrategyType.TargetSpend;

campaign.TargetSpend = new TargetSpend();

The API returns the error:

errors": [

      {

        "errorCode": {

          "fieldMaskError": "FIELD_HAS_SUBFIELDS"

        },

        "message": "The field mask updated a field with subfields: 'target_spend'.",

        "location": {

          "fieldPathElements": [

            {

              "fieldName": "operations",

              "index": 0

            }

          ]

But I don't receive the error when setting "campaign.TargetSpend.CpcBidCeilingMicros" to some value in the update call. 

I'm using the following way to call:

            return new CampaignOperation()

            {

                Update = CampaignToUpdate,

                UpdateMask = FieldMasks.AllSetFieldsOf(CampaignToUpdate)

            };

Is the behavior expected?

Hi Quan,

In order for our team to take a closer look at the error you encountered, could you also provide the complete request and response logs, with the request-id?

If you haven't yet, logging can be enabled by navigating to the Client libraries > Your client library (ex. Java) > Logging documentation, which you can access from this link. For .NET, you can check out this other link instead.

You may then send the requested information via the Reply privately to author option. If this option is not available, you may send the details directly to our googleadsa...@google.com alias instead.

Hi,

What is the default value of the  campaign.TargetSpend.CpcBidCeilingMicros ?  It seems I must set some value to bypass this issue. Can I put the value to be 0 if I don't want to specify a  CpcBidCeilingMicros ?

Thanks,

Quan

Hi Quan,

Thank you for the reply. I am also a member of the Google Ads API team and let me provide support to your concern.

Yes, you may try to set 0 to that field. Let me know how it goes after.

Hi Ernie,

Thanks for your reply. One more follow-up question. Can I set the  campaign.TargetSpend.CpcBidCeilingMicros = long.MAXVALUE  instead of 0 if I don't want to have the bid ceiling? Setting to 0 still gives me the error I showed in my original post

Hi Quan,

To investigate and to provide suggestions to your concern, could you provide the complete request and response logs with request ID and request header generated on your end with error when applying 0 to the CpcBidCeilingMicros?

You can provide it via Reply privately to author option. If this option is not available, then send it instead on this email address googleadsa...@google.com.

We are facing the same issue.
Before setting a cpc bid limit was optional.

I guess now is required?

Did you all solved this issue?

Hi Franklin,

Thank you for reaching out to us.

For our team to further investigate first, could you also please provide us with the complete API logs (request and response with request-id) generated on your end?

You may then send the requested logs via the Reply privately to author option. If this option is not available, you may send the details directly to our googleadsa...@google.com alias instead.

And for this, "Before setting a cpc bid limit was optional. I guess now is required?"
- This is still an optional field entered by the advertiser and specified in local micros. You may check this reference for more details.
