Validate 2 depth array on Laravel - laravel

Question

Is there a way to validate this array(), Nothing works so far:
[
{
"transaction": {
"user_id": 6,
"month": 12,
"year": 2084
},
"entities": [
{
"name": "Allan Botsford",
"value": 3,
"is_total": false,
"type": "CASH"
},
{
"name": "Luisa Schiller Sr.",
"value": 6266,
"is_total": false,
"type": "CASH"
},
{
"name": "Susie Deckow MD",
"value": 506700,
"is_total": false,
"type": "CASH"
}
]
},
{
"transaction": {
"user_id": 7,
"month": 5,
"year": 2002
},
"entities": [
{
"name": "Raquel Jast",
"value": 7,
"is_total": false,
"type": "CASH"
},
{
"name": "Wendell Herman I",
"value": 4480,
"is_total": false,
"type": "CASH"
},
{
"name": "Oceane Greenfelder DDS",
"value": 46344,
"is_total": false,
"type": "CASH"
}
]
}
]
I can validate the transaction with the following rules:
[
'*.transaction.month' => 'required|numeric',
'*.transaction.year' => 'required|numeric',
'*.transaction.transaction_date' => 'sometimes|date_format:Y-m-d'
]
The problem is in the nested entities array because the following rules are ignored:
return [
'*.entities.*.is_total' => 'required|boolean',
'*.entities.*.name' => 'required|string',
'*.entities.*.value' => 'required|numeric',
'*.entities.*.type' => ['required', Rule::in(CashTemporaryInvestment::TYPES)]
]
I don't find any hint on laravel documentation. I will appreciate any help. I am using Laravel 7

Laravel Validator wildcard will work using the following preg_match() as seen in the Validator class
$pattern = str_replace('\*', '([^\.]+)', preg_quote($this->getPrimaryAttribute($attribute), '/'));
So your pattern will work if you can access the attributes using
[0]['entities'][0]['is_total'] for your rule '*.entities.*.is_total' => 'required|boolean',
