4 years ago hi, thank you for your contribution. I've merged PR in off-the-github repository, hopefully i've not messed up with master too much (i promise to behave better next time ;)
I'd wait few more days if there are other issues found before releasing fixed version to pypi.
If 'fmt' is packed there should be values in 'attStmt'. This can cause certain servers to fail the registration (webauthn4j for example)
