IndexError: index 0 is out of bounds for axis 0 with size 0

Dear Diener,
I am trying to run model microbiota-wide metabolism with MICOM. I upload my tax data and then I build community models. However, it shows the problem below. Could you please help me with this issue?
Thank you very much.

  1. upload data
    import pandas as pd

metadata = pd.read_table("/content/data/MyDrive/hiv/dinh/metadatadinh.tsv").rename(columns={"sample-id": "sample_id"})

tax = pd.merge(tax, metadata, on="sample_id")

tax

  1. build model
    from micom.workflows import build
    from micom import Community
    import pandas as pd

Convert sample_id column to string type

tax['sample_id'] = tax['sample_id'].astype('str')

Call the build function

manifest = build(tax, "agora103_genus.qza", "models", solver="osqp",
cutoff=2.5e-2, threads=2)
