Not able to receive custom headers in webhooks

[fgarrec0397]

My goal is to follow the good practices by setting up webhooks, but I need to be able to receive custom data from the webhook call (like userId for example).

I tried to set custom headers on the request to retrieve it when the webhook is called and for this I followed the documentation.

const httpClient = new HTTPClient();

httpClient.addHook("beforeRequest", (req) => {
    const nextRequest = new Request(req, {
        signal: req.signal || AbortSignal.timeout(5000),
    });

    nextRequest.headers.set("x-custom-header", "custom value");

    return nextRequest;
});

const leonardo = new Leonardo({
    bearerAuth: process.env.LEONARDO_API_KEY,
    httpClient,
});

Am I on the good path here? Because it does not seem to work...

Thank you!
