Hi!

When we are importing new variants and we sometimes get url error:

Article import error: [CreateArticle] Validation error for Variant(SystemId: cc5f755c-df3a-460a-b96f-765dabd1c01f, Id: 02116090102), Localization[nb-NO].Url: ‘Value is not unique.’, Localization[en-US].Url: ‘Value is not unique.’, Localization[sv-SE].Url: ‘Value is not unique.’ and Localization[de-DE].Url: ‘Value is not unique.’

We are using the ISuggestionService to avoid this:

```
string url = urlSuggestions.Suggest(language.CultureInfo, suggestFrom);
_variant.Fields.AddOrUpdateValue("_url", language.CultureInfo, url);                            

```

Shouldn’t this guarantee that we get an unique url?

If not, how can we make sure the url is unique before saving the variant?

Suggest does check if the url is already taken, it only formats the provided string to a valid url.

An easy solution is to catch the specific error and keep trying to save with a suffix on the url (“url\_1”, “url\_2”).
