[shahradelahi]

The only thing that might not be compatible with the edge runtime of Next.js is undici, which is an HTTP client that is being used as the Node.js fetch API.

I'm not certain about how Next.js handles this, and I don't have any use cases. Please share details or error logs explaining what makes this library incompatible with the edge runtime.

Use Case

We're storing OAuth2 Client Credentials in Vault. Those credentials are used by next-auth api endpoints to allow users to log themself in and by the next-auth middleware to provide and update the user session. Right now we're using the fetch method provided by nextjs to load those secrets but we would love to use this package.

Error

I run into this error when creating a new instance of Client on Edge Runtime:
