Build errors when running gatsby build after using getServerData() for SSR page

Question

My site builds fine initially, but when trying to create a page that's SSR using getServerData while using gatsby-source-wordpress i get the following:

 ERROR #98001  ENGINE.VALIDATION
 Built Rendering Engines failed validation.
 
 Error, when running gatsby build. 

When setting the silent bool to false in Gatsby's validate engines util I get the following:

gatsby-source-wordpress  diff schemas
Validating Rendering Engines
error Error: [Immer] minified error nr: 18 'MapSet'. Find the full error at...

Gatsby build runs fine using the getServerData function, it's only when using it in-conjunction with gatsby-source-wordpress.

package.json:

    "dumper.js": "^1.3.1",

Ssr page:

import * as React from "react"
import { getPreviewPage } from "@api/preview"

    const Preview = ({ serverData }) => (
      <main>
        <h1>SSR page</h1>
        <h2>Page title: {serverData.title}</h2>
      </main>
    )
    
    export default Preview
    
    export async function getServerData({ query }) {
      const page = await getPreviewPage(query.id)
    
      return {
        props: page,
      }
    }
