Any import from next-sanity prevents Next.js static builds (output: 'export')

[dylansmith]

Describe the bug

We recently tried to build our Next.js (14.2.14) project using static exports via the output: 'export' config. However, the build kept failing with the error message:

> Server Actions are not supported with static export.

As the message says, you cannot render an app with Server Actions as a static site, but we were not using any server actions in our code. After hours of trying to figure out why Next was behaving this way, I isolated the issue to imports from next-sanity like these:

import { defineQuery } from 'next-sanity';

It appears as though the module packages/next-sanity/src/visual-editing/server-actions/index.ts is the culprit here. Possibly there is a chain of imports in place that whenever you import from next-sanity this module is resolved as well. In our case (as will be for many others using Sanity) our Next.js pages will run a query against Sanity on every page request so if the import from next-sanity is in this codepath then all pages will not be able to be statically generated.

I was able to workaround this issue by changing the following imports:

// import { defineQuery } from 'next-sanity';
import { defineQuery } from 'groq';

// import { groq } from 'next-sanity';
import groq from 'groq'`;

// import { createClient } from 'next-sanity';
import { createClient, SanityClient } from '@sanity/client';

To Reproduce

Steps to reproduce the behavior:

Add an import from next-sanity to any Next.js page or a module that is imported into a page, e.g.

import { defineQuery } from 'next-sanity';
import { groq } from 'next-sanity';

Expected behavior

Imports from next-sanity that are unrelated to visual editing should not break static builds in Next.js.
