Which version of jams are you using, and do you know which version of jams was used to create the file you're trying to load? Can you post a link to the jams file?

[irisyupingren]

pip3 freeze | grep jams jams==0.3.2

And the files are here: https://github.com/irisyupingren/HEMANanalysis/tree/master/data_jams

Thanks for looking into it :)

The problem here is that your curator fields do not conform to the schema. Curator fields are structured (name and email), not plain strings.

I think JAMS should not have let you save these files without a warning / error to that effect -- did that happen, or did you write these by hand using json?

Oh thanks! I used this script for parsing to jams https://github.com/urinieto/jams-data/blob/master/parsers/heman_parser.py Will do a pull request there :D

I'm late to the party, but I'll take the mea culpa for having written that Heman script. Apologies!
