Hi team,

I'm currently reviewing this pull request and will provide a full review shortly. In the meantime, here's a quick summary for you and other reviewers to get up to speed:

This pull request, chore(appengine): remove older region tag, aims to remove outdated region tags from the appengine/building-an-app/update/server.js file. The intent is to clean up the code and improve maintainability by removing redundant comments related to enabling URL-encoded body parsing. Specifically, the change removes two comment blocks, // [START enable_parser] and // [END enable_parser], which are no longer necessary.

Here's a breakdown of the changes:

• File Changed: appengine/building-an-app/update/server.js
• Lines Changed: Lines 25-30 were modified. The before and after snippets show the removal of the redundant comment blocks.

Before:

25:// [START enable_parser]
26:// [START gae_enable_parser]
27:// This middleware is available in Express v4.16.0 onwards
28:app.use(express.urlencoded({extended: true}));
29:// [END gae_enable_parser]
30:// [END enable_parser]

After:

25:// [START gae_enable_parser]
26:// This middleware is available in Express v4.16.0 onwards
27:app.use(express.urlencoded({extended: true}));
28:// [END gae_enable_parser]

The pull request also references a bug fix (b/392915923), suggesting this cleanup is likely part of a larger effort to address that issue.

I'll have a more detailed review shortly. Thanks!

A little haiku to brighten your day:

Code clean and bright,
Old tags vanish from the sight,
Fresh code takes its place.
