I don't know how to debug this further. @Will-Cooper , advice?

[Will-Cooper]

The website will be reading the file through the use of astrodbkit:

t_spectra: Table = db.query(db.Spectra).\
        filter(db.Spectra.c.source == query).\
        table(spectra=['access_url'])

My initial thought is that astrodbkit might be pointing to the previous version of specutils, @dr-rodriguez?

I'm not sure why the initial attempt is not considering all possible formats and only uses the ones defined in astrodbkit. Maybe the more recent versions of specutils need something to be set so that it includes default loaders as well.

Regardless, the MIRI spectra is ultimately loaded. The errors are from the txt and csv files.
