Why is required_if validation not working?

Question

Laravel

'form' => 'bail|required|array',
'form.type' => 'bail|required|string|in:one,two',
'form.method' => 'bail|required_if:form.type,one|string|min:1|max:8',

The request comes:

form [
   'type' => 'two',
   'method'' => '',
]

But the validation swears that method must be a string and at least 1 character. Why??? In the same place before this is required_if
Or is required_if somehow not working with nested parameters? Since the type key is in the form key Is
required_if:form.type not working?

Answer 1

Because required has no effect on other rules. Need nullable.
