Can you share the value of body that gets passed into verifyAttestationResponse() as credential? That error is thrown here:

https://github.com/MasterKale/SimpleWebAuthn/blob/master/packages/server/src/attestation/verifyAttestationResponse.ts#L67

This method assumes you're using @simplewebauthn/browser's startAttestation() method to perform attestation on the client. As part of encoding the authenticator's response to a JSON-friendly format, the rawId buffer is encoded to base64url within startAttestation(). Since id is the base64url-encoded value of rawId, they should match.

If you're not using @simplewebauthn/browser in your project you should be able to still use verifyAttestationResponse() if you make sure body.rawId is base64url-encoded to match body.id before passing it in.
