Some collection types are not been rendering in the sitemap

I’m using this plugin at a sitemap in my site, but I get a bug:

I set all collection types in the settings:

As can be seen, both Tags and Categories are collection types with a valid UID field(slug), but, navigation to the site map, we get this:

No trace of tags or categories, even though there are at least five records in each.

I tested this both in local and production but i am getting the same result. I thought it could be because of the draft system, but both tags and categories do not use this feature.

What could be the problem then?

PD: there is also another collection type which not use a uid field but i would like to add to the sitemap, is there any way to do that?

Thanks

@boazpoolman Thanks.

@SalahAdDin This plugin is by design an integration of the UID field type. Rewriting it to allow all field types would require a lot of work, and also I am of the opinion that only “seo-friendly” URLs should be used in a sitemap, instead of ID based URLs. These URLs are (as the name would suggest) SEO friendly, an that is what a sitemap is for anyways; to improve your SEO.

I will create another issue for this, to see if more people would want this feature.
