How to update image asset to an app campaign

['Rita Wang' via AdWords API and Google Ads API Forum]

Hi,

A key API use case of the client is to optimize the campaign by
replacing the bad performance assets with new one.

When client try to modify the image assets to an AC campaign via Adwords
API, they met following issue.
Since the headlines and descriptions are mandatory with Operators: ADD (ss
<https://screenshot.googleplex.com/WGVAMUthzNz>), the client made a try
with Operator: SET:

const operations = [{
        operator: 'SET',
        operand: {
            adGroupId: data.adGroup.id <http://data.adgroup.id/>,
            status: 'ENABLED',
            policySummary: {},
            labels: [],
            baseCampaignId: data.campaignId,
            baseAdGroupId: data.adGroup.id <http://data.adgroup.id/>,
            forwardCompatibilityMap: [],
            adStrengthInfo: {},
            ad: {
                images: [{
                    asset: {
                        'xsi:type': 'ImageAsset',
                        assetId: '647xxxxx11',
                    },
                }],
            },
        },
    }];
    const ret = await adGroupAdService.mutate({operations: operations});

Get error:

Error: cvc-complex-type.2.4.d: Invalid content was found starting with
element 'ad'. No child element is expected at this point.



Would you provide a code sample to the client?
