How to edit the default validation message in laravel?

Question

I have server validation below:

$this->validate([
    'first_name' => ['required','min:2','max:30',new PersonNameRule],
    'last_name' => ['required','min:2','max:30',new PersonNameRule],
    'username' => ['required','confirmed',new UsernameRule],
    'password' => 'required|confirmed|min:6|max:20',
    'birthdate' => ['required','date',new EligibleAgeRule(21)]
]);

In front-end, I intentionally fail the validation and console.log() the errors. The log returned looks like below:

Now my question is, where is the message (The given data was invalid) came from? Can I customize it?

If you want to do like this make sure you accepting 'application/json' — void

I don't know about your objective but if your finding the file. Its in the directory ..\Illuminate\Validation\ValidationException.php.

You can edit the message you mention inside the __construct method. See example below:

public function __construct($validator, $response = null, $errorBag = 'default') {
    parent::__construct('The given data was invalid.'); //change the message here

    $this->response = $response;
    $this->errorBag = $errorBag;
    $this->validator = $validator;
}
