Updating FeedItemAttribute Values

[Andi Jankovic]

Hi,

I am following step by step in python the guide to update attribute values in a feed:
https://github.com/googleads/google-ads-python/blob/99b99e560b4ab6c28e0e16e8d92d1e077f6d7f15/examples/feeds/update_flights_feed_item_string_attribute_value.py

However, I keep getting the issue of:

errors {

  error_code {

    field_mask_error: FIELD_MASK_MISSING

  }

  message: "Cannot use empty field mask in update operation."

  location {

    field_path_elements {

      field_name: "operations"

      index: 0

    }

  }

Yet my code runs smoothly but there seems to be some issues when I'm copying the update_mask. Here is my code

feed_item_operation = adwords_client.get_type("FeedItemOperation")
feed_item_service = adwords_client.get_service("FeedItemService")
adwords_client.copy_from(feed_item_operation.update, feed_item)
updated_feed_item = feed_item_operation.update
adwords_client.copy_from(updated_feed_item.attribute_values[x], all_attributes[x])

# Create a field mask using the old feed_item and the updated_feed_item.
adwords_client.copy_from(
feed_item_operation.update_mask,
protobuf_helpers.field_mask(feed_item._pb, updated_feed_item._pb),
)

# Create a field mask using the old feed_item and the updated_feed_item.
feed_item_operation.update_mask.CopyFrom(
protobuf_helpers.field_mask(feed_item._pb, updated_feed_item._pb)
)

# Mutate the feeds.
response = feed_item_service.mutate_feed_items(
customer_id=client_customer_id, operations=[feed_item_operation]
)
print(
"Feed item with resource name: "
f"'{response.results[0].resource_name}' and ID: "
f"'{x}' was updated."
)

Either there is something wrong in the documentation or I'm doing something wrong. How can my field_mask be missing when everything else is completely the same as in documentation.

Thank you.

Actually after looking deeper, if they're use copy_from with an attribute that doesnt have values changes, the whole code breaks.

Also, why is there a duplication of code in the documentation? Check documentation.
