Error when connecting to Dataverse with nested metadata blocks: KeyError: 'none'

[vera]

It seems that easyDataverse currently has no support for nested metadata blocks with nesting level > 2 (i.e. a compound field nested within another compound field). An error occurs when trying to connect to a Dataverse with such a block enabled.

Error log:

KeyError: 'none'

I'd be interested in how difficult you think it would be to add support for that, and whether it's planned?
