Error: expectation did not contain value for 'userHandle'

[lilac-milena]

When I try to call the assertionResult function, I got the following error:

Here's some contextual code that may be relevant to the issue:

const assertionExpectations = {
        // Remove the following comment if allowCredentials has been added into authnOptions so the credential received will be validate against allowCredentials array.
        // allowCredentials: [],
        // userVerification: "required",
        challenge: systemFunction.base64ToUint8Array(challenge),
        origin: "https://*",
        factor: "either",
        publicKey: logingAccount["publicKey"],
        prevCounter: logingAccount["counter"]
    };

    const keyDataDecoded = {
        rawId: systemFunction.base64ToArrayBuffer(keyData.rawId),
        response: {
            authenticatorData: systemFunction.base64ToArrayBuffer(keyData.response.authenticatorData),
            signature: systemFunction.base64ToArrayBuffer(keyData.response.signature),
            userHandle: systemFunction.base64ToArrayBuffer(keyData.response.userHandle),
            clientDataJSON: systemFunction.base64ToArrayBuffer(keyData.response.clientDataJSON),
        },
        id: keyData.id,
        type: keyData.type,
    }

    //console.log(keyDataDecoded)

    const authnResult = await f2l.assertionResult(keyDataDecoded, assertionExpectations);

const f2l = new Fido2Lib({
    timeout: 42000,
    rpId: "*",
    rpName: "Identity",
    // rpIcon: "https://example.com/logo.png",
    challengeSize: 128,
    attestation: "none",
    cryptoParams: [-7, -257],
    // authenticatorAttachment: "cross-platform",
    authenticatorRequireResidentKey: true,
    requireResidentKey: true,
    userVerification: "required"
    // requireResidentKey: true,
    // authenticatorUserVerification: "required"
});

I've checked my runtime environment, I'm using the Webauthn debugging tool for Chrome to debug, and the debugging tool shows that the "User Handle" parameter is already available

No, they're not related, it's a separate issue.

In your "assertionExpectations" JSON, include the user's userHandle, which is the user's ID used at signup encoded as base64url.
