Issue with Opennext Cloudflare

[himanshu-ntml]

Thank you so much for all the effort you’ve put into this. I am currently trying to integrate with OpenNext Cloudflare, but I’m encountering an error in the stream.ts file due to a missing index.js file in the pg-cloudflare package.

I have tried looking into the package and found in export there is default and workerd. Somehow it not working on nextjs.

Here is the error:

    The module "./dist/index.js" was not found on the file system:
  
      .worker-next/.next/standalone/node_modules/pg-cloudflare/package.json:13:15:

    You can mark the path "pg-cloudflare" as external to exclude it from the bundle, which will
  remove this error. You can also surround this "require" call with a try/catch block to handle this
  failure at run-time instead of bundle-time.
