Uploading data to openneuro - channels units

I am trying to upload a dataset created by MNE-BIDS for EEG/iEEG data onto OpenNeuro. However, I keep getting this error, which suggested to me that my channels.tsv sidecar files are improper. However, they all consist of uV, mV, or n/a, which looks correct to me. The error message isn’t very informative since I don’t see any A_hat in any of my files.

Perhaps I’m missing something here?
