Hi team,

I'm currently reviewing this pull request and will provide a full review shortly. In the meantime, here's a summary to help you and other reviewers quickly understand the changes:

This pull request, submitted by @hivanalejandro, aims to migrate the region identifier from appengine_websockets_yaml to gae_websockets_yaml. This change addresses issue b/391843837.

Here's a breakdown of the changes:

• Files Modified:

  • appengine/websockets/app.yaml: The appengine_websockets_yaml identifier has been replaced with gae_websockets_yaml in both the [START] and [END] comments (lines 1, 13).
  • datacatalog/cloud-client/createFilesetEntry.js: Removed redundant // [START datacatalog_create_fileset_tag] and // [END datacatalog_create_fileset_tag] comments (lines 30, 104).
  • datacatalog/quickstart/createFilesetEntry.js: Removed redundant // [START datacatalog_create_fileset_quickstart_tag] and // [END datacatalog_create_fileset_quickstart_tag] comments (lines 30, 128).

• Overall Intent: The primary goal is to update the region identifier for consistency and potentially to reflect changes in Google Cloud's internal naming conventions. The removal of the redundant comments in the datacatalog samples appears to be a secondary, unrelated change.

I'll provide a more detailed review shortly, including a check of the tests and lint results.

This pull request migrates region tags from "appengine_websockets_yaml" to "gae_websockets_yaml" and removes redundant tag "datacatalog_create_fileset_tag" in createFilesetEntry.js files. The changes are straightforward and improve consistency. The commit message clearly describes the changes and references the relevant issue. The checklist is mostly complete, but some items might not be applicable. Overall, the changes are well-done and easy to review.

Here's a summary of the style guide elements I referenced:

• Region tag naming: Region tags should follow the pattern [PRODUCT]_[SOLUTION]_REGION_TAG where REGION_TAG is a short descriptor, like yaml. In this case, the new tag gae_websockets_yaml adheres to this convention.
• Redundant tags: Avoid redundant region tags. If a code snippet is already covered by a more general tag, a more specific tag is not needed. Removing datacatalog_create_fileset_tag follows this guideline.

needs to be the year that this was added versus 2025. ETA: Based on blame this should be 2018.
