Laravel passport create token doesnt work on plesk server - laravel

Question

I use passport in my laravel project to authenticate users by api. API work correctly on my local host. But after i deploy it on Plesk server token doesnt create. Always show Server Error.
public function login(Request $request) {
$validator = Validator::make($request->all(),[
'email' => 'required',
'password' => 'required',
]);
if($validator->fails()) {
return response()->json(["validation errors" => $validator->errors()]);
}
$email = $request->email;
$password = $request->password;
error_log($password);
$user = DB::table("users")->where([["email", "=", $email]])->first();
if(is_null($user)) {
return response()->json(["success" => false, "message" => "User doesn't exist"]);
}
if(Auth::attempt(['email' => request('email'), 'password' => request('password')])) {
$user = Auth::user();
$token = $user->createToken('token')->accessToken;
$success['success'] = true;
$success['user'] = $user;
$success['message'] = "Success! you are logged in successfully";
$success['token'] = $token;
return response()->json(['success' => $success ], 200);
} else {
return response()->json(['error' => 'Unauthorised'], 401);
}
}
$token = $user->createToken('token')->accessToken;
This line throw error

Answer 1

Problem was in my AuthServiceProvider
class AuthServiceProvider extends ServiceProvider
{
protected $policies = [
'Medicare\Model' => 'Medicare\Policies\ModelPolicy',
];
public function boot()
{
$this->registerPolicies();
Passport::routes();
//
}
}
After i commented 'Medicare\Model' => 'Medicare\Policies\ModelPolicy' everything works fine.
