Passkey Failed to verify authentication

Hi, I am facing an issue where my password manager prompts me to use passkey when page use Conditional UI. Error: Unexpected authentication response challenge "AB", expected "AA" This is my auth config 
passkey({
  rpID: new URL(env.NEXT_PUBLIC_BASE_URL).hostname,
  rpName: siteConfig.name,
  origin: env.NEXT_PUBLIC_BASE_URL,
})
passkey({
  rpID: new URL(env.NEXT_PUBLIC_BASE_URL).hostname,
  rpName: siteConfig.name,
  origin: env.NEXT_PUBLIC_BASE_URL,
})

I'm experiencing the same issue. I noticed that the ExpiresAt value in the database appears to be static for every attempt and in the past (server start time?). I'm not sure if that's relevant or not. I can't see to get passkeys to work in my development environment. I got it to work using the below. Which doesn't matter to me in basic development, but not sure this is the right production solution. 
    passkey({
      authenticatorSelection: {
        userVerification: 'discouraged',
      },
    }),
    passkey({
      authenticatorSelection: {
        userVerification: 'discouraged',
      },
    }),
Hmm, no that doesn't do it either. I guess sometimes it works and sometimes it doesn't. I'm perplexed.
