SubtleCryptoProvider cannot be used in a synchronous context

[lapwat]

Having this error when receiving a webhook:

CryptoProviderOnlySupportsAsyncError: SubtleCryptoProvider cannot be used in a synchronous context.
Use `await constructEventAsync(...)` instead of `constructEvent(...)`

Context

It happens in the bun 1.3.9 runtime in production.

It does not happen in the node 25 runtime.

{
    "@golevelup/nestjs-stripe": "1.2.0",
    "stripe": "20.3.1",
}

@lapwat This seems to be a bug that was also at Stripe-node. Besides that, you've reported Node 25/Bun but we haven't been testing bun much.

If you're using Node 24 or above, we can try to take a stab but we'll need a reproduction

Here is the reproduction:

https://github.com/lapwat/stripebugrepro

1. Clone the repo
2. Setup your Stripe keys in app.module.ts
3. bun install <== Can be done in Dockerfile but I have no internet during build time
4. docker build -t nestjs-stripe-repo .
5. docker run --rm -it -p 3000:3000 nestjs-stripe-repo
6. Start stripe listener stripe-cli listen --forward-to localhost:3000/stripe/webhook
7. Trigger the event stripe-cli trigger customer.subscription.created

@lapwat The fix has been deployed with the latest version, could you confirm me that it works as intended for your use case?

It works great thank you
