Error trying to sync to cloud (code based workflow)

Ive made an ExpressJS api and ive setup an endpoint /novu. Ive publish my app on subdomain.mydomain.com but when I try to sync manually with subdomain.mydomain.com/novu my logs :

[Error]: Unknown BridgeError: crypto is not defined

@loup Can you share @novu/framework version?

loupOP•6d ago

Im using this one "@novu/framework": "^2.4.0",

Richard Fontein•6d ago

Thanks @loup , could you please also share which Node version you are using?

loupOP•6d ago

v23.1.0 Wait its my local version I should test on my VPS

Richard Fontein•6d ago

Yes, the deployed Bridge Node version will be great thanks. I suspect we may need to add a polyfill for crypto in older Node versions.

loupOP•6d ago

node -v v18.20.2 Im using Coolify btw for hosting my express api (idk if it change something)

Richard Fontein•6d ago

Got it, thanks. The crypto global is only available with Node 20+, are you able to upgrade your Node version to solve in the meantime? We will look at adding a polyfill for older versions

loupOP•6d ago

okay I need to make a custom Dockerfile (I was using nixpack), Im gonna check that thx a lot !

Richard Fontein•6d ago

Perfect! As a heads up, Node 18 reaches end of life on 30 April 2025, so it's generally a good idea to update.

I have raised an issue that we'll address in the next week or so.

its working with node 22. Im facing to another issue :

{
    "statusCode": 400,
    "timestamp": "2024-11-13T10:22:17.860Z",
    "path": "/v1/bridge/sync?source=studio",
    "message": "Signature does not match the expected signature. Please ensure the signature provided in the `novu-signature` header is correct and try again.",
    "error": "Bad Request"
}

    "message": "Signature does not match the expected signature. Please ensure the signature provided in the `novu-signature` header is correct and try again.",
    "error": "Bad Request"
}

I was thinkg novu framework automatically handle the signature header, docs :

The Novu-Signature header included in each signed event contains a timestamp and one or more signatures that we verify. The timestamp is prefixed by t=, and each signature is prefixed by a scheme. Schemes start with v, followed by an integer. Currently, the only valid live signature scheme is v1.

Handling the signature verification is done by the Novu Framework, so you don’t need to perform any action.

@loup are you using the EU or US cloud deployment of novu? Also, please verify that you have a proper NOVU_SECRET_KEY defined in your environment
