GitHub configPath import fails before opening static example #4695

Description

A public GitHub import with configPath stays at “Cloning repo from GitHub” / “Mounting environment in StackBlitz”, then displays “Something went wrong with this repository.” The editor and preview never open.

Reproduction

Open this exact-commit import in Chrome:
https://stackblitz.com/github/arcmira/integrations/tree/4427ec030b5539a6b2b34d91f6595872af490a86?configPath=examples/quote-timeline&file=fixture.js

The error was observed November 6, 2026, including after a reload. The public example directory contains package.json, package-lock.json and static HTML/CSS/JavaScript. Its dev script is serve . --listen 8080 --no-clipboard, using pinned serve 14.2.6. The repository root has no package.json.

Expected

Import the directory selected by configPath, install its dependencies and run its dev script, as described in the GitHub import guide.

Context

npm ci --ignore-scripts, all four example tests and the local static-server check pass. No API key or backend is needed to open the example. Is a root configuration also required for this repository layout, or is the importer failing before it reads configPath?
