Fatal error saving posts: WP_Error::get_data() in class-astra-elementor.php

Hi there,

I’m running into a fatal error that’s preventing me from saving or publishing posts in WordPress. The error appears in my server’s error log and coincides exactly with the “The response is not a valid JSON response” error I see in the block editor when trying to update a post.

Error details:

PHP Fatal error: Uncaught Error: Call to undefined method WP_Error::get_data() in
/wp-content/themes/astra/inc/compatibility/class-astra-elementor.php:388

Environment:

• Astra theme version: 4.13.5
• Elementor version: 4.1.4
• This happens on both new posts and existing posts, so it doesn’t appear to be content-specific.
• I’ve already ruled out plugin conflicts (tested with all other plugins deactivated) and confirmed the WordPress REST API itself is working correctly.
• Temporarily switching to the Twenty Twenty-Four theme allows posts to save without issue, which points to this being an Astra/Elementor compatibility conflict specifically.

This may be related to a missing check before calling get_data() on a WP_Error object (rather than a proper WP_REST_Response) — similar to a bug pattern I’ve seen mentioned in other plugin fixes.

Could someone confirm if this is a known issue, and if a fix is planned? Happy to provide any additional debug info if needed.

Thanks!
