I am new to laravel and working on apis, I have made an api in which i have implemented validation.Everything is working fine but i am stuck on a little thing. I want to to change the key name in the validation error. For example For the “unique” validation error. This is what now showing

I want to rename “email”(text) key with “message”(text)
I have tried so many thing in illuminate/support/validation.php
messagebag.php file but if it changes then error show of “data undefined”.
The links i followed are
Override laravel validation message
This is the validation code
$validator = Validator::make($request->all(), [
'first_name' => 'required',
'last_name' => 'required',
'email' => 'required|email|unique:users',
'fcm_token' => 'required',
'password' => 'required',
'c_password' => 'required|same:password'
]);
You can manually loop over the error Message Bag and construct the response to replace a key
$validator = Validator::make($request->all(), [
‘first_name’ => ‘required’,
‘last_name’ => ‘required’,
’email’ => ‘required|email|unique:users’,
‘fcm_token’ => ‘required’,
‘password’ => ‘required’,
‘c_password’ => ‘required|same:password’
]);
$errors = [];
foreach ($validator->errors()->messages() as $key => $value) {
if($key == ’email’)
$key = ‘message’;
$errors[$key] = is array($value) ? implode(‘,’, $value) : $value;
//implode is for when you have multiple errors for a same key
//like email should valid as well as unique
}
$result = array(“status” => count($errors)?0:1, ‘data’=>$errors);
return $result;
