try this:

AdminForgotPasswordController.php

class AdminForgotPasswordController extends Controller
{
use SendsPasswordResetEmails;


protected function broker(){
    return Password::broker('admins');
}

public function sendResetLinkEmail(Request $request){
    $input = $request->all();
    $rules = array(
        'email' => "required",
    );
    $validator = Validator::make($input, $rules);
    if ($validator->fails()) {
        $arr = array("status" => 400, "message" => $validator->errors()->first());
    } else {

        // check if user already exists
        $users = Admins::all();
        if(!$users->isEmpty()){
            foreach($users as $user){
                if($user->email == $request['email']){
                break;
            }
            $user = false;
        }
        }else{
        $user = false;
        }

    if(!$user){
        $arr = array("status" => 400, "message" => "That user doesn't exist");
        return \Response::json($arr);
    }


    // create reset pass token
    $token = Password::getRepository()->create($user);
    $user->notify(new SendResetPasswordAdmin($token,$user->email));
    $arr = array("status" => 200, "message" => "Email to reset password sent");
    return \Response::json($arr);
}


}

}

And you need create SendResetPasswordAdmin on app/notifications whir this command php artisan make:notification SendResetPasswordAdmins

class SendResetPasswordAdmins extends Notification
{
use Queueable;

/**
 * Create a new notification instance.
 *
 * @return void
 */
public function __construct($token,$email)
{
    $this->token = $token;
    $this->email = $email;    
}


public function via($notifiable)
{
    return ['mail'];
}


public function toMail($notifiable)
{
    return (new MailMessage)
                ->line(Yourmessage)
                ->action('Message2', route('admins.password.reset', ['token' =>$this->token, 'email' => $this->email]))
                ->line(FooterMessage);
}

Route:

 Route::get('admins/password/reset/{token}/{email}', 
 'ResetPasswordAdmins@showResetForm')->name('admins.password.reset');

And this:

class ResetPasswordAdmins extends Controller
 {
public function showResetForm($token,$email){   
return view(yourView)->with(['token' => $token, 'email' 
=> $email]);
}

public function updatePass(Request $request){
//Here your logic and validator
}

i found it solution.. Problem was in auth.php folder i was using providers instead of provider so this error appears. just check config/auth.php and replace this code.

'passwords' => [
    'users' => [
        'provider' => 'users',
        'table' => 'password_resets',
        'expire' => 60,
        'throttle' => 60,
    ],
    'admins'=>[
        'provider'=>'admins',
        'table'=>'password_resets',
        'expire'=>60,
        'throttle'=>60,
    ],
],
