Error: json_encode error: Malformed UTF-8 characters

[mxkyu]

I have this error with lots of production data (it contains large json data):
GuzzleHttp\Exception\InvalidArgumentException: json_encode error: Malformed UTF-8 characters, possibly incorrectly encoded in /app/vendor/guzzlehttp/guzzle/src/Utils.php:299
In stack trace i found:
#4 /app/vendor/jkocik/laravel-profiler/src/Processors/BroadcastingProcessor.php(57): GuzzleHttp\Client->request('POST', 'http://localhos...', Array)
In file src/Processors/BroadcastingProcessor.php on line 57 i must do mb_convert_encoding():
mb_convert_encoding($dataTracker->data()->toArray(), 'UTF-8', 'UTF-8'),
and it works without any error.

Can you fix it feature versions?
