UnboundLocalError when running minimal_media with `summarize=False`

When using the second dataframe output from complete_db_medium and summing up the fluxes per metabolite as the medium file for grow, most communities couldn't grow (the flux values seemed too low)

I also tried getting the per-sample results using the minimal_media function with summarize=False, but I'm receiving this error after 100%:

from micom.workflows import minimal_media

minimal_media_persample = minimal_media(manual_amplicon_manifest, summarize=False,
                    model_folder="/projectnb/dietzelab/zrwerbin/N-cycle/data/MICOM/manual_amplicon/", 
                          min_growth=.01,threads=28)

Running ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 100% 0:04:52
