Fatal error: ($object_id) must be of type int, null given

I started to get this error whenever I tried to add a new term of a custom taxonomy that uses a custom table to store some extra fields: 'storage_type' => 'custom_table'.

Fatal error: Uncaught Error: MetaBox\CustomTable\Cache::get(): Argument #1 ($object_id) must be of type int, null given, called in /public/wp-content/plugins/meta-box-aio/vendor/meta-box/mb-custom-table/src/Storage.php on line 29
