Hi, I created a PIN for my Nitrokey 3C NFC and Nitrokey 3A NFC (at https://webauthn.bin.coffee/). I then tested creating a credential with my both of these keys at https://webauthn.bin.coffee/ in Windows in the Firefox browser, but it fails:
Contacting token... please perform your verification gesture (e.g., touch it, or plug it in) Note: Raw response in console. :: "None" Attestation Format :: Got error: RangeError: offset is outside the bounds of the DataView Failures: 1 TODOs: 0
However, I get green results when I try the same procedure on my android phone via NFC and via USB, Both For the Credential creation and the Get Assertion.
