Error message

[CsiAudrey]

Hi,
I tried to run this code in qiime2:
qiime sourcetracker2 barplot
--i-proportions qiime2-results/sourcetracker-loo/mixing_proportions.qza
--m-sample-metadata-file sample-metadata4.tsv
--o-visualization qiime2-results/sourcetracker-loo/proportions-barplot.qzv

And I keep getting the same error no matter how I change my metadata. I used keemei to verify my metadata and there were no problem with it. The error message is:
'DataFrame' object has no attribute ''ids''

Do you know what I can do to fix the error?

Thank you :)
