Issue with Nuxt Server API Call "Cannot read from private field"

[CalebKester]

I recently updated my packages from 1.8.1 to latest and found out that in 1.9 I am unable to make calls from a file in server/api due to the following issue. Did something change on how I need to make this call from nuxt server?

Error:

File: /server/api/footer.ts

export default defineEventHandler(async (event) => {
  const query = groq`*[_type == 'page' && defined(slug)]{
        _id,
        title,
        'url': '/' + slug.current,
    }`;

  const sanity = useSanity();

  const data = await sanity.fetch(query);

  return data;
});

Package.json

  "dependencies": {
    "@nuxtjs/sanity": "^1.10.1",
    "nuxt": "^3.11.1",
    "vue": "^3.4.21",
    "vue-router": "^4.3.0"
  }

Nuxt Config:

export default defineNuxtConfig({
  devtools: { enabled: true },

  nitro: {
    preset: "azure",
  },
  modules: ["@nuxtjs/sanity"],
  sanity: {
    projectId: "xxxxxx",
    dataset: "production",
    apiVersion: "2021-10-21",
  },
});

Try setting minimal: true explicitly - it looks like previously you might have been relying on it falling back to minimal client as you had no @sanity/client installed.

[CalebKester]

I added this to my package "@sanity/client": "^6.15.7", in my sandbox repo (it was in my main repo that has this issue) and it's still having the issue.

However minimal: true does make it work both with the sanity client added and without it.

Thanks for the quick help!

[danielroe]

We still need to investigate why this is failing with the sanity client. Do you have any more logs or a reproduction?

[CalebKester]

I've moved my sandbox repo over to github and you can see it here https://github.com/CalebKester/nuxt-sanity-server . You can test it with the url http://localhost:3000/api/footer and toggling minimal on and off will error it.

Same error!

[stephanepericat]

same issue here

[plcdnl]

@stephanepericat as workaround you can use minimal: true

[stephanepericat]

@plcdnl reverting to 1.8.3 also solves the issue

[xuzuodong]

According to the error message and related files in the error stack, this is may be because, somewhere in v1.9.0 updates, SanityClient is been wrapped by a Proxy, and in such case, SanityClient can no longer visit its private field under the hood.

Turns out this line breaks using useSanity from server.
