"id" field of PublicKeyCredentialDescriptor is wrongly typed

[Ponjimon]

It should be of type BufferSource. I would suggest just removing it from the code alltogether since PublicKeyCredentialDescriptor is a global type anyway and is already included in TypeScript in lib.dom.d.ts

ref

webauthn-lib/packages/server/src/typed/webauthn.ts

Line 39 in a09b6f3

id: string;

The problem is communication from server-side to client-side, all buffer decoded into base64 format. That why "id" in there was string not buffer.
