Why are facets populated with GUIDs instead of the metadata values in Sitecore?
I created a facet based on a field that is referencing another Sitecore item. The facet is displaying the GUIDs of those referenced items instead of their metadata values.
Thereâs two options for this. You can either use foreign keys, but this is an experimental feature, that isnât fully complete. The way we recommend is to create a computed field that will get the related items and simply return their metadata values.
