the last week my php flex app on app-engine has been causing error 500, sometimes. I dont have changed nothing in my code. But the strangest is that nothing is shown in the error reporting panel. Someone knows if there are new updates or something like that for App Engine?.
Regards.
Finally, I found the error logs of my app, they are in Stackdriver Logs Viewer. And not in the Error Reporting Panel
Blessings.
