I often see useless errors like "A dependency injection object is required to access the 'response' service", but where it throws? How can I locate the incorrect code?
In your public/index.php, at the end of the file, you'll see a try/catch block, you can print the backtrace there to see where the exception is generated:
try {
//...
} catch (Exception $e) {
echo $e->getMessage(), '<br>';
echo $e->getTraceAsString(), '<br>';
}Thanks :)
