Error after updating to Sanity 3.4.0, fixed by changing import from rxjs to rxjs/operators.

import client from "part:@sanity/base/client";

const { dataset } = client.config();

import { getCliClient } from "sanity/cli";

const previewSecret = "SANITY_PREVIEW_SECRET";

// Replace `remoteUrl` with your deployed <https://www.sanity.io/nextjs-cms|Next.js> site
const remoteUrl = `<https://site.netlify.app>`;
const localUrl = `<http://localhost:3000>`;
const stagingUrl = `<https://staging--site.netlify.app/>`;

const getBaseURL = () => {
  const dataset = "staging";
  const hostname = window.location.hostname;

  if (hostname === "localhost") {
    return localUrl;
  }

  if (dataset === "production") {
    return remoteUrl;
  }

  return stagingUrl;
};

export default function resolveProductionUrl(doc) {
  const baseUrl = getBaseURL();
  const previewUrl = new URL(baseUrl);

  const client = getCliClient({ apiVersion: "2023-1-03" });

  console.log(client);

  previewUrl.pathname = `/api/preview`;
  previewUrl.searchParams.append(`secret`, previewSecret);
  previewUrl.searchParams.append(`type`, doc?._type);
  previewUrl.searchParams.append(`slug`, doc?.slug?.current ?? `/`);

  return previewUrl.toString();
}
