raw app ${ref.path} has no compiled bundle — deploy it first

Error message

raw app ${ref.path} has no compiled bundle — deploy it first

What it means

When exporting a raw app to the Hub, the session fetches the app's compiled JS bundle at /api/w/<workspace>/apps/get_data/v/<secret>.js. A non-OK response means the raw app has never been deployed (no compiled bundle exists), and deploying an app without a bundle to the Hub would ship an empty/broken artifact, so it throws this error.

Solutions

1. Deploy the raw app first (Deploy button / push the app), then retry the Hub export
2. Verify ref.path points to the app's deployed path in the correct workspace
3. Check you have permission to read the app's compiled assets in that workspace

Example fix

// before
await session.exportToHub(ref)  // app never deployed
// after
await deployApp(workspace, ref.path)  // ensures compiled bundle exists
await session.exportToHub(ref)

const app = await AppService.getApp({ workspace, path: ref.path })
if (!app || app.no_version) throw new Error(`Deploy ${ref.path} before exporting to Hub`)

try {
  await session.exportToHub(ref)
} catch (e) {
  if (String(e.message).includes('has no compiled bundle')) {
    // trigger app deployment, then retry the export
  }
}

When it happens

Trigger: saveApp/raw-app export path fetches the bundle JS and jsRes.ok is false — the app at ref.path exists but was never deployed (draft-only), was deployed under a different workspace, or the fetch 404s because the compiled asset is missing.

Common situations: Editing a raw app locally and exporting to Hub without ever hitting Deploy; the app was undeployed or its deployment deleted; a stale reference pointing at an app path that no longer has a published version.
