Did you sorted it ?
The update() method should be used without the encoding (“utf8”) and the output encoding (“hex”).
Try that:

const genHash = crypto .createHmac("sha256", process.env.SHOPIFY_API_SECRET) .update(JSON.stringify(req.body)) .digest("base64");

This is incorrect because the update() method only takes one argument, which is the data you want to hash. The encoding is specified when calling the digest() method, as you did correctly with .digest(“base64”).
