Error: No data when runnning verifyAuthenticationResponse about simplewebauthn HOT 2 CLOSED

We figured out what was wrong:

We are storing the device in a MongoDB and authenticator.credentialPublicKey needs to be converted to Binary before storing. Afterwards you need to convert it back to a Uint8Array and then it works. Otherwise the data is corrupted.

//before storing
credentialPublicKey: new Binary(credentialPublicKey)

//after query
credentialPublicKey = new Uint8Array(credentialPublicKey.buffer)

To try and connect some dots here, this seems related to the following discussion where this same issue is solved in a similar manner:

MongoDB Authenticator types: Discussion #375

Note to self if this comes up again: I wonder if there's something I can do here to help out MongoDB users...
