It was used to identify the solution after the fix raised in Automattic/wp-cli-sqlite-command#24 uncovered the issue.

Proposed Changes

PHP 8.5 triggers a deprecation notice from react/promise inside wp-cli.phar. Studio treats any stderr output as a fatal export failure, so the notice was causing the export to fail even though the actual export succeeded. This PR ensures that we filter out the deprecation warning from the actual fatal error:

Error invoking remote method 'exportSiteForPush': Error: Database export      
  failed: PHP Deprecated: Case statements followed by a semicolon (;) are       
  deprecated, use a colon (:) instead in                                        
  phar:///tmp/wp-cli.phar/vendor/react/promise/src/functions.php on line 369

This would ideally need to be fixed upstream but I think this fix should be sufficient for now.

Testing Instructions

Ensure that you have a newly created site with PHP version 8.5
First, you will need to apply the instructions from Load polyfills correctly for the new sqlite version (v2.2.22) wp-cli-sqlite-command#24 to uncover this issue
Once you see that the push fails due to the deprecation warning, pull the changes from this branch
Navigate to the Sync tab
Connect a WP.com site
Do the push process
Confirm that the push process succeeds

Pre-merge Checklist

Have you checked for TypeScript, React or other console errors?

We now have two importer/exporter implementations: one in apps/cli and another in apps/studio.

In apps/cli, we only throw if WP-CLI returned a non-zero exit code, which I believe is the correct way to handle errors there.

I say let's do the same thing here.

@fredrikekelund the issue should now be addressed, let me know if you have any further comments.

LGTM 👍 I'd probably make the equivalent change in apps/studio/src/lib/import-export/export/exporters/default-exporter.ts, too. Full-site exports already work when I test it with a PHP 8.5 site, but this change would ensure correctness.

Should now be done 👍

The agent only needs product_slug, is_free, and expired to gate features, since the system prompt hardcodes what each plan tier can and can't do. Strip plan.features and keep only essential plan properties. * Also compact large array responses by stripping content and _links List endpoints like GET /templates can return 80K+ chars of block markup. Strip content and _links from array items when the response exceeds 80K chars — the agent can still identify items by slug/title and fetch individual ones for full content. * Add _fields prompt guidance and scope plan compaction as special case Add system prompt hint instructing the agent to use _fields on wp/v2 listing endpoints to minimize response sizes. Scope compactResponse() to only handle plan.features stripping with a clear comment that this is a special case (the API doesn't support sub-field filtering). Remove the generic array compaction in favor of prompt-driven field selection. * Add fields guidance for v1.1, rename stripOversizedFields Update system prompt to instruct the agent to use fields (v1.1) and _fields (wp/v2) to minimize response sizes, always including ID for v1.1 requests. Rename compactResponse to stripOversizedFields for clarity. * Remove indentation in JSON to save tokens * Fix dark mode visibility for error/success text in site list (#3034) * Fix dark mode onbiarding screen (#3025) Co-authored-by: Kateryna Kodonenko <kateryna@automattic.com> * Studio: Filter out deprecated warnings from fatal errors (#3018) * Filter out deprecated warnings from fatal errors * Ensure our error filtering approach is consistent with CLI * Apply changes to default exporter * Fix unit tests --------- Co-authored-by: Kateryna Kodonenko <kateryna@automattic.com> * [skip ci] Update translations * [skip ci] Bump version to 1.7.8-beta1 * CLI: ensure Studio root exists before starting code agent (#3039) * Ensure startAiAgent() checks whether ~/Studio exists before launching the Claude SDK. * Define a localeData type to fix lint error: The inferred type of this node exceeds the maximum length the compiler will serialize.
