How to update image_ad?

[xiaochuan li]

I want to modify the image of an image_ad type ad with a given `ad_id`. When I use AdService to modify it, the following error occurs:
(<_InactiveRpcError of RPC that terminated with:
        status = StatusCode.INVALID_ARGUMENT
        details = "Request contains an invalid argument."
        debug_error_string = "UNKNOWN:Error received from peer ipv4:127.0.0.1:7777 {created_time:"2025-05-19T05:42:15.5886834+00:00", grpc_status:3, grpc_message:"Request contains an invalid argument."}"

  location {
    field_path_elements {
      field_name: "operations"
      index: 0
    }
    field_path_elements {
      field_name: "update"
    }
    field_path_elements {
      field_name: "image_ad"
    }
    field_path_elements {
      field_name: "data"
    }
  }
}
request_id: "Sgw2tFrYlXQu6OkrrofwZQ"
, 'Sgw2tFrYlXQu6OkrrofwZQ')

Do I need to set the current image_ad to "REMOVED" and then create a new one? In this case, will the ad_id also change? Please explain to me the correct process of modifying the image in image_ad.

Hi,

Thank you for reaching out to the Google Ads API support team.

From the provided logs, you are encountering the IMMUTABLE_FIELD error indicating that the 'image_ad.data' field cannot be updated. To change the image ad, you will need to remove the old image ad and create a new one, which will also result in a new ad ID. I would recommend you to check this mutating ads and Ad type compatibility for more information. 
 

Thanks,
