Partition Metrics - Access nested JSON Field

[bkhkcm]

• Laravel Version: ^10.0
• Nova Version: 4.26.5
• PHP Version: 8.2.4
• Database Driver & Version: pdo_mysql, mysqlnd 8.2.4

Description:

In my partition metric I want to access a nested JSON field.

public function calculate(NovaRequest $request) {
  return $this->count($request, User::class, 'meta->notifications->newsletters');
}

However, I don't get any correct data back.

If I make a query directly to the database:

SELECT JSON_UNQUOTE(JSON_EXTRACT(meta, '$.notifications.newsletters')) AS opt, COUNT(*) as aggregate FROM users GROUP BY opt;

Do I get the following data:

opt	aggregate
true	58
false	13
NULL	1

It seems that in the file /vendor/laravel/nova/src/Metrics/Partition.php, when calling the function formatAggregateResult, an empty string is passed for $key.
