Field $facets was not indexed with SortedSetDocValues

[BramvdBogaard]

I'm using the newest beta 4.0.0-beta1 to use faceted searches (which is awesome!)

Unfortunately I've made my site multilingual (added Dutch to the default English) and now I keep getting the error Field $facets was not indexed with SortedSetDocValues.

In my query I add the following steps, in which I add 5 faceted fields.

var result = query .OrderBy(IsDescending(request.OrderBy), GetOrderFields(request.OrderBy)) .WithFacets(facets => { facets.FacetString(Defaults.ExternalIndex.TrainingFields.RelatedAudience); facets.FacetString(Defaults.ExternalIndex.TrainingFields.RelatedLocation); facets.FacetString(Defaults.ExternalIndex.TrainingFields.RelatedPartner); facets.FacetString(Defaults.ExternalIndex.TrainingFields.RelatedTimezone); facets.FacetString(Defaults.ExternalIndex.TrainingFields.RelatedTraining); }) .Execute(queryOptions);

I've registered the Facets like this:

`var facetsConfig = new FacetsConfig();

        facetsConfig.DimConfigs.Add(Defaults.ExternalIndex.TrainingFields.RelatedAudience, new FacetsConfig.DimConfig { IsMultiValued = true });
        facetsConfig.DimConfigs.Add(Defaults.ExternalIndex.TrainingFields.RelatedLocation, new FacetsConfig.DimConfig { IsMultiValued = true });
        facetsConfig.DimConfigs.Add(Defaults.ExternalIndex.TrainingFields.RelatedPartner, new FacetsConfig.DimConfig { IsMultiValued = true });
        facetsConfig.DimConfigs.Add(Defaults.ExternalIndex.TrainingFields.RelatedTimezone, new FacetsConfig.DimConfig { IsMultiValued = true });
        facetsConfig.DimConfigs.Add(Defaults.ExternalIndex.TrainingFields.RelatedTraining, new FacetsConfig.DimConfig { IsMultiValued = true }); `

The fieldTypes are all FacetFullText options.FieldDefinitions.AddOrUpdate(new FieldDefinition(Defaults.ExternalIndex.TrainingFields.RelatedAudience, FieldDefinitionTypes.FacetFullText)); options.FieldDefinitions.AddOrUpdate(new FieldDefinition(Defaults.ExternalIndex.TrainingFields.RelatedLocation, FieldDefinitionTypes.FacetFullText)); options.FieldDefinitions.AddOrUpdate(new FieldDefinition(Defaults.ExternalIndex.TrainingFields.RelatedPartner, FieldDefinitionTypes.FacetFullText)); options.FieldDefinitions.AddOrUpdate(new FieldDefinition(Defaults.ExternalIndex.TrainingFields.RelatedTimezone, FieldDefinitionTypes.FacetFullText)); options.FieldDefinitions.AddOrUpdate(new FieldDefinition(Defaults.ExternalIndex.TrainingFields.RelatedTraining, FieldDefinitionTypes.FacetFullText));

Am I doing something wrong or did I run into a bug in Examine? Thanks in advance
