Hi folks! Getting this error "sha256 checksum of body does not match", while trying to parse received webhook's content. here is my webhook:

const receiver = new WebhookReceiver(process.env.LIVEKIT_API_KEY!, process.env.LIVEKIT_API_SECRET!);

// Middleware to handle 'application/webhook+json' content type
const webhookJsonParser = express.json({
  type: ['application/json', 'application/webhook+json']
});

<http://router.post|router.post>('/lk-webhook', webhookJsonParser, async (req, res) => {
    try {
        console.log('Received webhook with content type:', req.get('content-type'));
        console.log('Authorization:', req.get('Authorization'));

        const event = await receiver.receive(req.body, req.get('Authorization'));
        console.log('Webhook event:', event);
        res.status(200).json({ message: 'ok' });
    } catch (ex) {
        console.error('Error processing webhook:', ex);
        res.status(500).json({
            message: 'Failed to handle webhook',
            error: ex instanceof Error ? ex.message : 'Unknown error'
        });
    }
});

I triple checked my API key, both in my env key and the one I used while creating webhook are the same
