It appears a very old version of the facebook/php-business-sdk was being used which wasn’t php8.1 compatible. I updated the composer.json file in the plugins root directory by removing the dev requirements as I couldn’t figure out the proper combination and then updated the facebook/php-business-sdk version (https://packagist.org/packages/facebook/php-business-sdk).

After updating the composer.json I removed the composer.lock file and ran?composer update?which updated the package and appears to have resolved the issue.
