according to laravel documentation 8 you must to set nullable rule for example:

 $validated = $request->validate([
            'firstName' => ['required','max:255'],
            'lastName' => ['required','max:255'],
            'branches' => ['required'],
            'services' => ['required' , 'json'],
            'contract' => ['required' , 'max:255'],
            'FixSalary' => ['nullable','numeric' , 'max:90000000'],
            'Percent' => ['nullable','numeric' , 'max:100'],
        ]);

in your case :

$this->validate($request, [
        'provinces_id' => 'required|numeric',
        'type' => 'required',
        'bed' => 'nullable|numeric',
]);

In laravel 5.5 or versions after it, we begin to use nullable instead of sometimes.

In Laravel 6 or 5.8, you should use nullable. But sometimes keyword doesn't work on that versions.

You may need nullable – sometimes and present didn't work for me when combined with integer|min:0 on a standard text input type - the integer error was always triggered.

A Note on Optional Fields

By default, Laravel includes the TrimStrings and ConvertEmptyStringsToNull middleware in your application's global middleware stack. These middleware are listed in the stack by the App\Http\Kernel class. Because of this, you will often need to mark your "optional" request fields as nullable if you do not want the validator to consider null values as invalid.

Tested with Laravel 6.0-dev

Use sometimes instead of required in validation rules. It checks if only there is a value. Otherwise it treats parameter as optional.

If I understood you correctly, you're looking for sometimes rule:

'bed' => 'sometimes|numeric',

In some situations, you may wish to run validation checks against a field only if that field is present in the input array. To quickly accomplish this, add the sometimes rule to your rule list
