I think I know now what's going on in #2466. In summary, datasets from two different rootpaths might have different facets in the input directory DRS which may lead to different types of the facet values.

Unfortunately, this PR does not fix that problem; I am still getting the same errors.

this looks good to me, not sure about its actual utility, in light of Manu's comment, but approving from an engineering point 👍
