Inconsistency with `transports` property type

[aaroned]

I noticed the transports property types differ between the Authenticator and WebAuthnAuthenticator interfaces. One is string and the other a string[].

This leads to inconsistency in the way the strategy is configured (getUserAuthenticators vs getAuthenticatorById). Could both be string[]?

interface WebAuthnAuthenticator {
    id: string;
    transports: string[];
}
export interface Authenticator {
    id: string;
    userId: string;
    publicKey: string;
    counter: number;
    credentialDeviceType: string;
    credentialBackedUp: boolean;
    transports: string;
    aaguid: string;
}
