export const queryClient = postgres(process.env.DATABASE_URL);
export const db = drizzle({
    client: queryClient,
    schema,
    logger: false,
    casing: "snake_case",
  });

  });

Error: Cannot perform I/O on behalf of a different request. I/O objects (such as streams, request/response bodies, and others) created in the context of one request handler cannot be accessed from a different request’s handler. This is a limitation of Cloudflare Workers which allows us to improve overall performance.
