Laravel Response::json failing

Question

I'm trying to send a JSON Response from the server by passing an array to Response::json() but I keep getting the UTF-8 Invalid Argument in vendor\laravel\ ... \jsonReponse.php At line 49

public function getAllForInbox() {

    $conn = SqlServerPdo::connect();

    $query = "Some Query";

    $statement = $conn->prepare($query);

    $success = $statement->execute();

    $result = $statement->fetchAll(PDO::FETCH_ASSOC);

    SqlServerPdo::disconnect();

    return Response::json($result);

}

Everything else works fine. I did a var_dump on $result. IS an array containing arrays of data. Each array being a row from the result.

The thing is .... It was working perfectly.... then I ran Composer Update ... and now it doesn't work anymore o.O ... could it be some error on the vendor/laravel folder???

In fact, I have a local development server running, and it works just fine, when I upload to the server currently hosting the App, it doesn't... could it be PHP???

this is and example $result var dump

array(10) {
  [0]=>
  array(6) {
    ["numint"]=>
    string(1) "1"
    ["name"]=>
    string(15) "Sistel Helpdesk"
    ["priority"]=>
    string(1) "0"
    ["assignation"]=>
    string(0) ""
    ["tickets_open"]=>
    string(1) "1"
    ["tickets_with_conv"]=>
    string(1) "0"
  }
...

And 9 other results

Its probably some non UTF-8 string in your database.

When the Response::json() tries to run - it fails because of non UTF8.

You need to cycle through your array and run utf8_enconde() on all the results before passing it to Response::json()
