cannot create shopping product groups tree in one batch

[Inilien Inilien]

I am using Python google-ads library for Google Ads API v2 (Beta)

Using test account I am trying to create 3 product Groups in an empty AdGroup.

I have been able to successfully create root single ProductGroup with type `UNIT` but cannot create `SUBDIVISION` ones.

Here are my AdGroupCriterionOperation protobuf messages:

[create {
   resource_name: "customers/5936312994/adGroupCriteria/82410873572~-25"
   status: PAUSED
   ad_group {
     value: "customers/5936312994/adGroups/82410873572"
   }
   listing_group {
     type: SUBDIVISION
   }
 }, create {
   resource_name: "customers/5936312994/adGroupCriteria/82410873572~-27"
   status: ENABLED
   ad_group {
     value: "customers/5936312994/adGroups/82410873572"
   }
   negative {
     value: true
   }
   listing_group {
     type: UNIT
     case_value {
       listing_custom_attribute {
         index: INDEX0
       }
     }
     parent_ad_group_criterion {
       value: "customers/5936312994/adGroupCriteria/82410873572~-25"
     }
   }
 }, create {
   resource_name: "customers/5936312994/adGroupCriteria/82410873572~-26"
   status: ENABLED
   ad_group {
     value: "customers/5936312994/adGroups/82410873572"
   }
   cpc_bid_micros {
     value: 10000000
   }
   listing_group {
     type: UNIT
     case_value {
       listing_custom_attribute {
         value {
           value: "1000-2000"
         }
         index: INDEX0
       }
     }
     parent_ad_group_criterion {
       value: "customers/5936312994/adGroupCriteria/82410873572~-25"
     }
   }
 }]

When I am trying to call mutate method of AdGroupCriterionService I am getting 3 errors (one for each of the operations above).

for the root operation I am getting `LISTING_GROUP_SUBDIVISION_REQUIRES_OTHERS_CASE` and for both children I am getting: `LISTING_GROUP_DOES_NOT_EXIST`

Here are the exact messages:

errors {
  error_code {
    ad_group_criterion_error: LISTING_GROUP_SUBDIVISION_REQUIRES_OTHERS_CASE
  }
  message: "Subdivided listing groups must have an \"others\" case."
  trigger {
    string_value: "ProductPartition{id=TempCriterionId{id=25}, bidSimulatorStatus=null, partitionType=SUBDIVISION, parentCriterionId=null, productGroup=null, productGroupObsoleteStatus=null, caseValue=null, decisionPath=[], salesCountry=null, merchantId=null, hasPromotedSuggestion=null}"
  }
}
errors {
  error_code {
    ad_group_criterion_error: LISTING_GROUP_DOES_NOT_EXIST
  }
  message: "Listing group referenced in the operation was not found in the ad group."
  trigger {
    string_value: "TempCriterionId{id=25}"
  }
  location {
    field_path_elements {
      field_name: "operations"
      index {
      }
    }
    field_path_elements {
      field_name: "create"
    }
    field_path_elements {
      field_name: "listing_group"
    }
    field_path_elements {
      field_name: "parent_ad_group_criterion"
    }
  }
}
errors {
  error_code {
    ad_group_criterion_error: LISTING_GROUP_DOES_NOT_EXIST
  }
  message: "Listing group referenced in the operation was not found in the ad group."
  trigger {
    string_value: "TempCriterionId{id=25}"
  }
  location {
    field_path_elements {
      field_name: "operations"
      index {
        value: 1
      }
    }
    field_path_elements {
      field_name: "create"
    }
    field_path_elements {
      field_name: "listing_group"
    }
    field_path_elements {
      field_name: "parent_ad_group_criterion"
    }
  }
}

I am assuming that if the root AdGroupCriterion was successful then both children criterions would be created as well. But I cannot figure out how to change my operation in order to create the root AdGroupCriterion with `SUBDIVISION` listing_group type.

The messages I am trying to create in my testing account are the exact copies from the production account.

And I didn't find any differences concerning listing_group logic in Java example of creation several ProductGroups at once from the API docs.
