Wrangler with Stripe Error

Developers Workers

Can not test my stripe webhook in localhost.

 [ERROR] Uncaught (in promise) TypeError: crypto2.createHmac is not a function

  .createHmac('sha256', secret)
   ^
      at computeHMACSignature
  (/Users/e****/node_modules/stripe/lib/crypto/NodeCryptoProvider.js:11:7)
      at verifyHeader
  (/Users/e****/node_modules/stripe/lib/Webhooks.js:88:45)
      at constructEvent
  (/Users/e****/node_modules/stripe/lib/Webhooks.js:10:19)
      at fetch (/Users/e****/src/index.ts:40:34)

I also updated my wrangler and added
workers_dev = true
node_compat = true

Still, issue continues.

Thank you that was the solution.

const event = stripe.webhooks.constructEvent(body, sig, endpointSecret)

To

const webCrypto = Stripe.createSubtleCryptoProvider();
const event = await stripe.webhooks.constructEventAsync(body, sig, endpointSecret, undefined, webCrypto)
