array_merge(): Argument #1 must be of type

Hi,

When connect to the admin we got this error :

Fatal error: Uncaught TypeError: array_merge(): Argument #1 must be of type array, null given in /www/<private>/html/wp-content/plugins/seo-by-rank-math/includes/modules/content-ai/class-event-scheduler.php:96

This error seems to be cause by CloudFlare. This request in the class-event-scheduler.php :

$data        = wp_remote_get( 'https://rankmath.com/wp-json/contentai/v1/defaultPrompts' );

Return this :

Error 1015

And at line 96 you try to merge json_decode($data). But json_decode($data) is not an array.

update_option( 'rank_math_content_ai_prompts', array_merge( json_decode( $data, true ), $custom_prompts ) );

After disable Content AI Module problem disapear.
You should maybe decode then test if result is a array before merge.

A temporary solution is to :

1. In file /www/<private>/html/wp-content/plugins/seo-by-rank-math/includes/modules/content-ai/class-event-scheduler.php:96 comment the line :
   update_option( ‘rank_math_content_ai_prompts’, array_merge( json_decode( $data, true ), $custom_prompts ) );
2. Disable Content AI Module
3. Uncomment the line
4. Then wait the plugin update 🙂

Bests,
Sébastien.
