Description:

When I goto Resource A
Then I create it's relationship Resource B
So that the url has viaResource=a&viaResourceId=1
And in Resource B, BelongsTo field is disabled.

Then in depends on the $request('b') is null
And calculations that take resource b into account here fail.

But if I am creating Resource B directly, without viaResource=a&viaResourceId=1 in my url
Then depends on is working fine

class Sale extends NovaResource {
...
BelongsTo::make('Client'),
Number::make('Total'),
Number::make('Commission')->dependsOn(['client'], function (Currency $field, NovaRequest $request, FormData $formData) {
    // Here the $request->get('client') is NULL, even though it's selected
    $client = Client::find($request->get('client'));
    if ($client?->rate_type === 'percentage') {
        $field->value = $client->rate_agreed * $formData->total / 100;
    }
})
...
}
