TypeError: Cannot read properties of undefined (reading 'token') on auth pages (e.g. /login.php)

[SamuelCook]

Description

Navigating to any auth page (e.g. /login.php) while running stencil start
results in a 500 error. The local server crashes with:

  TypeError: Cannot read properties of undefined (reading 'token')
      at internals.parseResponse (server/plugins/renderer/renderer.module.js:222:81)

Root Cause

In parseResponse, the CLI unconditionally reads settings.storefront_api.token
to fetch Page Builder regions via GraphQL:

  if (pageType) {
      regionResponse = await contentApiClient.getRenderedRegionsByPageType({
          accessToken: response2.data.context.settings.storefront_api.token,
          ...
      });
  }

BigCommerce does not include storefront_api in the page context for auth pages
(login, create account, forgot password, etc.). This makes storefront_api
undefined, and the .token access throws.

Steps to Reproduce

1. Run stencil start against any store
2. Navigate to http://localhost:3000/login.php
3. Observe 500 response and the TypeError in the terminal

Expected Behaviour

Auth pages render normally. They contain no Page Builder regions requiring a
Storefront API token, so the GraphQL fetch should be skipped or handled gracefully.

Suggested Fix

Guard before the fetch:

  if (pageType && response2.data.context.settings.storefront_api) {

Or use optional chaining:

  accessToken: response2.data.context.settings.storefront_api?.token,

Environment

• @bigcommerce/stencil-cli: 9.0.1 (also present in 9.0.0)
• Node.js: v24.14.1
• OS: macOS
• Affected pages: /login.php and any auth page where BigCommerce omits
  storefront_api from the context
