Solve problem use "nullable":
public function rules()
{
return [
'field' => 'nullable|url',
];
}

when we submmitting values from js, like through a FormData, the value null could be submitted as string containing 'null', which may pass a nullable rule, cause further type check fail. so be sure to make this value be posted as '', literaly nothing, no a 'null' string

can you be more specific and show a code example to resolve the error in this situation?

This is beyond the scope of server-side validation. I think we shouldn't be adding null values to FormData in the first place -- either it's specifically an empty string (per the user's input) or the value is absent/omitted altogether.
Add sometimes rule to the validation. This means to validate it for a URL when the value is not given or null.
public function rules()
{
return [
'field' => 'sometimes|url',
];
}

don`t work ... In Laravel docs "run validation checks against a field only if that field is present in the input array". Field present in array but have an empty value.
When you use formData (js) to submit your request, "null" is assigned by default for all empty fields. This will pass through Laravel "nullable" validaton and indicate as invalid input. So, please, use something like below in your validation rules.
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
$rules = [];
if($this->filled('field') && $this->field!= 'null'){
$rules['field'] = 'url';
}
return $rules;
}
In order to do this use laravel's form requests. https://laravel.com/docs/8.x/validation#creating-form-requests
