Fatal error json_decode()

Hi,

I have a fatal error thrown by my Instagram Feed plugin (free version – v.6.10.1).
The website is working but I can see the error in my error log and I think it is causing issues with the cron jobs.

Here is the full error :

PHP Fatal error:  Uncaught TypeError: json_decode(): Argument #1 ($json) must be of type string, array given in /wp-content/plugins/instagram-feed/inc/Helpers/SB_Instagram_Tracking.php:129
