UNEXPECTED_INTERNAL_API_ERROR - Ad Customizers - mutate

Based on the v201509 of Adwords API with dotnet and C#, I'm having an UNEXPECTED_INTERNAL_API_ERROR exception when I'm calling the mutate method.

The mutate call executes (only) one operation which is supposed to edit the ad customizer feed name. The exception is thrown between 2 and 5 times, then the instruction is executed 'normally'.

The same problem happens when I'm trying to add a new column to the ad customizer feed.

I read the documentation about UNEXPECTED_INTERNAL_API_ERROR. I'm suprised google ask us to re-execute the operation with a delay but this is not an option for us...

I guess this issue is well known since it appears in the documentation.

Do you plan to fix it? Do you have a solution to prevent it before it happens?

My code (check the attachment for a pretty view of this code + the exception detail) :

            AdCustomizerFeedService adCustomizerFeedService = (AdCustomizerFeedService)user.GetService(AdWordsService.v201509.AdCustomizerFeedService);

            Selector selector = new Selector

            {

                fields = new string[] { AdCustomizerFeed.Fields.FeedAttributes, AdCustomizerFeed.Fields.FeedId, AdCustomizerFeed.Fields.FeedName, AdCustomizerFeed.Fields.FeedStatus },

                predicates = new Predicate[] {

                    Predicate.Contains( AdCustomizerFeed.FilterableFields.FeedName, "MegaPromo"),

                    Predicate.Equals( AdCustomizerFeed.FilterableFields.FeedStatus, FeedStatus.ENABLED.ToString())

                }

            };

            AdCustomizerFeedPage page = adCustomizerFeedService.get(selector);

            if (page != null && page.entries != null && page.entries.Count() > 0)

            {

                AdCustomizerFeed adCustomizerFeed = page.entries[0];

                adCustomizerFeed.feedName = adCustomizerFeed.feedName + "|Edited ";

                AdCustomizerFeedOperation operation = new AdCustomizerFeedOperation

                {

                    operand = adCustomizerFeed,

                    @operator = Operator.SET,

                };

                AdCustomizerFeedReturnValue mutateResult = adCustomizerFeedService.mutate(new AdCustomizerFeedOperation[] { operation });

            }

Thanks for your support.

Regards.
