Translations ListTranslationsForArticle method throwing (404) Not Found Error

[sionjlewis]

Hi
About three weeks ago the following line of code is throwing an error:

GroupTranslationResponse translations = _helpCntrApi.Translations.ListTranslationsForArticle(articleID);

The error is as follows (minus organisation specific details):

System.Net.WebException

This exception was originally thrown at this call stack:
[External Code]

Inner Exception 1:
WebException: The remote server returned an error: (404) Not Found.

The code above the error seem to be working OK.

We are declaring global variables as the top of our class:

private const string _zenLocale = "en-nz";
private ZendeskApi _zenApi = null;
private IHelpCenterApi _helpCntrApi = null;

Instantiating the objects with the constructor:

_zenApi = new ZendeskApi(zenUrl, zenLogin, zenToken, _zenLocale);
_helpCntrApi = _zenApi.HelpCenter;

We do the stuff specific to our organisation, before get the article ID and then run the code that errors...

Int64 articleID = (long)article.Id;
GroupTranslationResponse translations = _helpCntrApi.Translations.ListTranslationsForArticle(articleID);
foreach (Translation translation in translations.Translations)
{
translation.Body = contents;
_helpCntrApi.Translations.UpdateArticleTranslation(translation);
}

If I craft the URL to be what I would expect the Translations.UpdateArticleTranslation(() method to use (see example below), and past into my browser, I see a lovely JSON response

https://ORGANISATION.zendesk.com/api/v2/help_center/articles/6800012345678/translations.json

Here is the JSON example:
