Solid Query: useQuery({ enabled: false }) hangs renderToStringAsync (SSR) on 5.101.0

[daviduzumeri]

Describe the bug

A useQuery with enabled: false never settles its underlying createResource during SSR, so renderToStringAsync (and SolidStart's async/stream SSR) hangs as soon as the disabled query's .data is read during render.

On the server, solid-query forces experimental_prefetchInRender = true (useBaseQuery), so the observer result carries a .promise. For a disabled query that promise never resolves, and the resource fetcher returns it (via hydratableObserverResult) instead of short-circuiting — so the SSR render awaits a promise that can never settle.

Reproduces on @tanstack/solid-query@5.101.0 (latest) with solid-js@1.9.13.

Related, both closed and neither matching this exact symptom (single useQuery, SSR render hang): #6256, #7167.

Your minimal, reproducible example

Standalone Node ESM — no framework needed. solid-js/web resolves to its server build under Node's default node export condition, so isServer === true.

// repro.mjs  ->  node repro.mjs
import { renderToStringAsync, createComponent, Suspense } from 'solid-js/web'
import { QueryClient, QueryClientProvider, useQuery } from '@tanstack/solid-query'

const client = new QueryClient()

function Inner() {
  const q = useQuery(() => ({
    queryKey: ['disabled'],
    queryFn: () => Promise.resolve('data'), // never runs (disabled)
    enabled: false,
  }))
  return () => `data=${JSON.stringify(q.data)}` // reading data drives the resource
}

const App = () =>
  createComponent(QueryClientProvider, {
    client,
    get children() {
      return createComponent(Suspense, {
        get children() {
          return createComponent(Inner, {})
        },
      })
    },
  })

// The race timeout is ONLY so the script exits; renderToStringAsync never settles.
const html = await Promise.race([
  renderToStringAsync(() => createComponent(App, {})),
  new Promise((_, r) =>
    setTimeout(() => r(new Error('renderToStringAsync did not settle (5s)')), 5000),
  ),
])
console.log(html)

Steps to reproduce

1. npm i @tanstack/solid-query@5.101.0 solid-js@1.9.13
2. node repro.mjs
3. Observe it never resolves — the 5s race rejects with renderToStringAsync did not settle.

Expected behavior

A disabled query must not suspend SSR; the resource should resolve immediately with the idle state.

Possible fix

Short-circuiting enabled === false in the useBaseQuery resource fetcher — returning the synchronous result with the dangling .promise stripped — fixes it. Verified locally against 5.101.0:

// inside the createResource fetcher, before `return new Promise(...)`
const obs = observer()
if (obs.options.enabled === false) {
  const { promise, ...rest } = hydratableObserverResult(obs.getCurrentQuery(), observerResult)
  return rest
}

• unpatched: hangs (5s timeout above)
• with the short-circuit: resolves in ~25ms with the correct idle state

Happy to open a PR if this approach looks right — wanted to confirm the direction first, since it touches the core query path and enabled can also be reactive (this handles the literal false case).

Environment

@tanstack/solid-query@5.101.0, solid-js@1.9.13, Node 24.
