Cas v6.4+ exception with mfa-webauthn

[Benjamin Somers]

Hi,

I am configuring CAS for the webauthn MFA and as soon as a user tries to do the registration, they receive an error. You can find below the stacktrace corresponding to the error (the exception occurs as soon as the user clicks on the webauthn button on the provider selection screen). I have tried both v6.4 and v6.5. Am I missing something?

Thanks in advance

Ben
