[BUG] Not working with PayloadCMS

[ianlibanio]

Describe the bug

I am trying to use PayloadCMS with opennextjs-cloudflare. While running in dev mode everything works fine, but when trying to preview or deploy, when accessing any route it gives an error (Error: The Node.js process.exit(1) API was called. Canceling the request.) and no more info is provided.

Steps to reproduce

Just create a simple payloadcms project and try to deploy it using opennextjs-cloudflare, and it won't work.

Here is an minimal reproducible example:

It's expected for PayloadCMS to work with opennextjs-cloudflare.

@opennextjs/cloudflare version

1.0.0-beta.1

Wrangler version

4.8.0

Using vars defined in .dev.vars
▲ [WARNING]                             You have defined bindings to the following internal Durable Objects:

                                - {"name":"NEXT_CACHE_DO_QUEUE","class_name":"DOQueueHandler"}
                                These will not work in local development, but they should work in production.
  
                                If you want to develop these locally, you can define your DO in a separate Worker, with a
  separate configuration file.
                                For detailed instructions, refer to the Durable Objects section here:
  https://developers.cloudflare.com/workers/wrangler/api#supported-bindings


workerd/server/server.c++:1942: warning: A DurableObjectNamespace in the config referenced the class "DOQueueHandler", but no such Durable Object class is exported from the worker. Please make sure the class name matches, it is exported, and the class extends 'DurableObject'. Attempts to call to this Durable Object class will fail at runtime, but historically this was not a startup-time error. Future versions of workerd may make this a startup-time error.
