Module build failed: UnhandledSchemeError: Reading from "cloudflare:sockets" is not handled

For some reason, when I use the @prisma/adapter-pg and pass my Postgres connectionString, I get the following error? What could cause this? I'm just running locally using next dev?

I noticed, as soon as I just import the import { PrismaPg } from "@prisma/adapter-pg"; it will fail. Even when not instantiating it.

import { PrismaPg } from "@prisma/adapter-pg";
import { PrismaClient } from "@/prisma/generated";
import { env } from "@/env";

const adapter = new PrismaPg({ connectionString: env.DATABASE_URL });
const db = new PrismaClient({ adapter });
import { PrismaPg } from "@prisma/adapter-pg";
import { PrismaClient } from "@/prisma/generated";
import { env } from "@/env";

const adapter = new PrismaPg({ connectionString: env.DATABASE_URL });
const db = new PrismaClient({ adapter });
generator client {
  provider        = "prisma-client-js"
  output          = "../prisma/generated"
  previewFeatures = ["queryCompiler", "driverAdapters"]
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}
generator client {
  provider        = "prisma-client-js"
  output          = "../prisma/generated"
  previewFeatures = ["queryCompiler", "driverAdapters"]
}

datasource db {
  provider = "postgresql"

Yes, sorry for replying late. Don't mind to ping me in follow up questions. Are there any updates on this? Is this something I'm experiencing on my own ?
