fido2.ctap.CtapError when running solo1 key keyboard 'sequence'

[JonTheNiceGuy]

I received my Somu device today.

I installed the solo1 tool from pip, and then, following guidance from in here, I ran pip install fido2~=0.9.

I then ran the upgrade process, which, as others have noted, will fail on the first pass with (27264, b'') but a re-run succeeds.

When I tried to run solo1 key keyboard I repeatedly get this message:

solo1 key keyboard 'decafbad'

    raise CtapError(status)
fido2.ctap.CtapError: CTAP error: 0x01 - INVALID_COMMAND

Is this because the Somu can't run this keyboard command? Is it because there's an issue (which can be debugged and solved) or is there something else?

I have a Tap. I don't see anywhere in the firmware where this is even handled. I might be misreading the code but my brief delve looks like it should be handled somewhere in ctap_request ... but there's no mention of a command for this, no macros mentioning the command, nothing.

I suspect this simply isn't implemented on any device using this firmware.
