Passkeys issue, implemented using simplewebauthn

Hi

I was excited to see 1Password has come out with PassKey support as I am developing a website that uses simplewebauthn (npm) to bring up the security interface in both Safari and Chrome. I've had that working for a while but when I tried to get this working in both my development and staging server (hosted on AWS) I get errors from 1Password's extension.

Local errors:

Staging errors:

Any hints on why this is?
