List-credentials doesn't work anymore in 1.7.0+

On Nitrokey 3, I was able to use “nitropy fido2 list-credentials” to see all the residential credentials stored on the key.

After 1.7.0 this doesn’t work anymore and results in an error message:

Tested with Nitropy 0.4.45 and multiple Nitrokey 3 sticks.
With Firmware version 1.6.0 it was still working fine and with 1.7.0 and 1.7.2 it stopped working on all of them.

There is a “PIN_AUTH_INVALID” message but the PIN number is definately correct (worked on 1.6.0 with nitropy and does work in the browser when authentication with those credentials)

it works for me on the latest 1.7.2 firmware. you could send logs to support.
btw @Koren23 do you work for red hat ?

I can provide logs, of course. How can I create them and where should I send them?
Yes, I work for them but I am here solely on personal reasons. My account and presence on this forum is purely based on private / non professional usage.

the first post error you mentioned has got all the info about taking and sending logs.
Also you could join matrix support group which is usually more quick way to get support.
Would love to give any other input that would help.


Is this possibly related to this?
